Research Doctorate - Doctor of Philosophy (PhD)

The Volterra series is a powerful and versatile tool which can be used to model any nonlinear dynamical system that is time-invariant and has fading memory. The popularity of the series in system identification and control applications has been limited due to its complex multidimensional nature, and thus the large numbers of parameters required in a Volterra series model. Recent developments using Bayesian regularization techniques have increased the feasibility of Volterra series estimation from arbitrary time domain data records, however there are still several challenges remaining to enable widespread use of the series in identification and control. Three of these challenges in particular form the motivation for contributions in this thesis. The first challenge addressed in the thesis relates to Volterra series estimation from time domain data, and in particular when data records are short, noisy and arbitrary in nature. While the recently proposed Bayesian regularization approach represents significant progress, the method is still generally inaccurate or computationally intractable for series orders higher than 3. Two main factors cause these issues at high series orders, and they are the computational burden of the Bayesian optimization routine, and the sheer number of parameters required to be estimated. To combat these issues, a new expectation-maximization (EM) framework is proposed in this thesis to improve the computation time scaling (with series order) of the optimization problem. The new framework is then combined with a basis function approach to estimation, where the Volterra series terms are estimated using orthonormal basis function expansions. Simulation and practical examples highlight the improved feasibility and performance of the regularized basis function approach over existing methods in the literature. The second motivating challenge is to construct equivalent regularized methods for frequency domain identification of Volterra series models. There are several frequency domain representations available in the literature for Volterra series, and two of these models are considered in the thesis: Nonlinear Output Frequency Response Functions (NOFRFs) and Generalized Frequency Response Functions (GFRFs). An extension to the linear theory is proposed for estimating NOFRFs in the case where the system has a parallel Hammerstein structure. In this case, the NOFRF at each nonlinear order behaves like a linear filter. For the GFRFs, which are multidimensional analogs of the time domain Volterra series terms, a Bayesian estimation method is developed and designed to be equivalent to the time domain method available in the literature. Simulation examples confirm the benefits of each model's proposed method. An investigation is also performed to analyze the transient contributions in a nonlinear system's frequency domain response under arbitrary excitation. Analytic expressions are obtained in a highly structured manner, revealing valuable insight for…

Este trabajo de Tesis está enfocado en la identificación de sistemas no lineales de modelo dinámico no conocido, adicionalmente y en base a los resultados obtenidos, se propone la aplicación del sistema de Control Predictivo no Lineal Basado en Modelos, NMPC, usando el algoritmo de la Matriz Dinámica de Control no Lineal, NDMC. El primer objetivo de este trabajo consiste en implementar una metodología para la identificación de sistemas no lineales usando series de Volterra truncadas; proyectadas sobre una base de polinomios de Laguerre. Los criterios teóricos han sido validados mediante la identificación del sistema de fabricación de resina melamínica, mediante un reactor tipo batch, de PISOPAK PERU SAC. El sistema del reactor indicado ha sido modelado mediante el uso de kernels de primer, hasta tercer grado. En todos los casos los modelos obtenidos presentan un buen comportamiento a lo largo de todo el tiempo que dura el proceso de la producción de la resina melamínica. El segundo objetivo, de esta tesis consiste en utilizar el modelo identificado, para la formulación de un control NMPC basado en el algoritmo de la NDMC. Esta formulación teórica, se ha utilizado para la simulación de un controlador NMPC para el seguimiento de la trayectoria de la temperatura en el reactor R0-1 utilizado en la fabricación de resina melamínica. Adicionalmente se ha simulado el control de la trayectoria de la temperatura hasta alcanzar un set-point, en concordancia a las recomendaciones técnicas para la producción de la resina en el reactor bajo prueba. La simulación se realizó con referencias fija y variable. Los resultados de las simulaciones revelaron que el controlador NMPC propuesto tiene la capacidad para el seguimiento de la temperatura en el interior del reactor si la referencia es una función tangente hiperbólica. En este sentido, el sistema de control propuesto es muy prometedor para el control de procesos no lineales. En los procesos de identificación de sistemas no lineales, la aplicación del modelo de Volterra-Laguerre permite obtener modelos con un número reducido de parámetros, en lugar de los sistemas modelados con series de Volterra que contienen un número enorme de parámetros.

This thesis work, is focused on identifying nonlinear systems, when the dynamic models are unknown, and further based on the results, we propose the application of the Nonlinear Model Predictive Control, NMPC, using the algorithm of the Nonlinear Dynamic Matrix Control, NDMC. The first aim of this work is to propose a methodology for identification of nonlinear systems using truncated Volterra series, such that the Volterra kernels are projected on a basis of Laguerre polynomials. The theoretical criteria have been validated through the identification of the manufacturing system melamine resin, using a batch type reactor belong to PISOPAK PERU SAC. The reactor system on test has been modeled using kernels up to third degree. In all cases, the resulting models show good behavior throughout of the time process of resin production…

▼ Compressive-sensing techniques have gathered strength over the last decade since they overcome the requirements of the Nyquist-Shannon sampling theorem, asserting that a signal can be recovered from far fewer measurements than traditional methods use. In this field, the theory of graphical models has been applied to simplify the solving of large-scale regression problems. Such iterative algorithms as approximate message passing have been developed to solve problems with a high inner complexity in a simple computational manner. ☐ One of the topics where this techniques are really suitable is the nonlinear suppression in communications. Current trends in mobile communications systems seem to agree that matching a moderate increase of data rate with high spectral and power efficiencies are key challenges. New standards of wireless digital communications are pushing the design of power amplifiers (PAs) towards challenging requirements in terms of linearity and efficiency. 4G systems have also incorporated the advances accomplished during the last decade in the processing of spread spectrum and multicarrier signals, together with Multiple Input Multiple Output (MIMO) techniques. While these new systems demand active devices like PAs to work near saturation seeking power efficiency, the created nonlinearity may cause the overall system not to meet the requirements of out-of-band emissions and in-band distortion as well. The need of digital compensation techniques and evolution in the designing of new digital signal processing architectures make digital predistortion (DPD) a convenient linearization approach. Digital predistorters usually rely on behavioral models such as memory polynomials (MPs), generalized memory polynomials (GMPs), pruned Volterra series, etc. Volterra system identification suffer the "curse of dimensionality", since they tend to grow exponentially in number of coefficients as the memory and nonlinear orders become larger. Practical use of DPDs require pruning of the models, where only the most important coefficients of it are retained, selecting them by some criteria.

▼ Digital predistortion is one of the most cost effective ways among all linearization techniques. However, most of the existing designs treat the power amplifier as a memoryless device. For wideband or high power applications, the power amplifier exhibits memory effects, for which memoryless predistorters can achieve only limited linearization performance. In this dissertation, we propose novel predistorters and their parameter extraction algorithms. We investigate a Hammerstein predistorter, a memory polynomial predistorter, and a new combined model based predistorter. The Hammerstein predistorter is designed specifically for power amplifiers that can be modeled as a Wiener system. The memory polynomial predistorter can correct both the nonlinear distortions and the linear frequency response that may exist in the power amplifier. Real-time implementation aspects of the memory polynomial predistorter are also investigated. The new combined model includes the memory polynomial model and the Murray Hill model, thus extending the predistorter's ability to compensate for strong memory effects in the power amplifier. The predistorter models considered in this dissertation include both even- and odd-order nonlinear terms. By including these even-order nonlinear terms, we have a richer basis set, which offers appreciable improvement. In reality, however, the performance of a predistortion system can also be affected by the analog imperfections in the transmitter, which are introduced by the analog components; mostly analog filters and quadrature modulators. There are two common configurations for the upconversion chain in the transmitter: two-stage upconversion and direct upconversion. For a two-stage upconversion transmitter, we design a band-limited equalizer to compensate for the frequency response of the surface acoustic wave (SAW) filter which is usually employed in the IF stage. For a direct upconversion transmitter, we develop a model to describe the frequency-dependent gain/phase imbalance and dc offset. We then develop two methods to construct compensators for the imbalance and dc offset. These compensation techniques help to correct for the analog imperfections, which in turn improve the overall predistortion performance. Advisors/Committee Members: G. Tong Zhou (Committee Chair), J.

▼ Today’s advances in communication systems and VLSI circuits increases the performance requirements and complexity of circuits. The performance of RF and mixed-signal circuits is normally limited by the nonlinear behavior of the transistors used in the design. This makes simulation of nonlinear circuits more important. Volterra series is a method used for simulation of mildly nonlinear circuits. Using Volterra series the response of the nonlinear circuit is converted into a sum of multiple linear circuit responses. Thus, using Volterra series, simulation of nonlinear circuits in frequency-domain analysis becomes possible. However, Volterra series is not able to simulate strongly nonlinear circuits such as saturated Power Amplifiers. In this thesis, a new time-varying Volterra analysis is presented. The time-varying Volterra analysis is the generalization of conventional Volterra analysis where instead of using a DC expansion point a time-varying waveform has been used. Employing a time-varying expansion waveform for Volterra analysis, time-varying Volterra achieves better accuracy than conventional Volterra. The time-varying expansion waveforms are derived using a fast pre-analysis of the circuit. Using numerical examples, it has been shown that the time-varying Volterra is capable of simulating nonlinear circuits with better accuracy than conventional Volterra analysis. The time-varying Volterra analysis in both time and frequency domains are discussed in this thesis. The time-varying Volterra analysis has been used to simulate a saturated Class-F Power Amplifier in frequency-domain. The simulation results show good agreement with ELDO® steady-state and Harmonic Balance simulation results. The proposed method manages to simulate nonlinear circuits, such as saturated Power Amplifier, mixers and nonlinear microwave circuits, with good accuracy. Also, this method can be used to simulate circuit with large number of nonlinear elements without the convergence issues of Harmonic Balance.

[pt] Esta dissertação apresenta um desenvolvimento analítico que permite caracterizar as distorções produzidas na densidade espectral de potência de sinais OFDM devido à sua passagem através de sistemas não lineares. O processo estocástico que caracteriza a envoltória complexa de um sinal OFDM é odelado como um processo estocástico gaussiano complexo, próprio. A não linearidade do canal de transmissão é caracterizada pela expansão, em série de potências, de suas características de conversão AM/AM e AM/PM. Utilizando-se o Teorema dos Momentos para processos gaussianos complexos chega-se a expressões analíticas fechadas para a função autocorrelação e para a densidade espectral de potência do sinal produzido na saída da não- linearidade. As expressões obtidas são aplicadas a situações particulares nas quais 1, 2 e 3 sinais OFDM compartilham a não- linearidade permitindo quantificar, nestas situações específicas, as distorções correspondentes aos produtos de intermodulação de diferentes ordens e o efeito, nestas distorções, de variações no valor do back-off de entrada do sinal.

[en] This MSc dissertation presents a theoretical analysis that evaluates the distortion experienced by the power spectrum density of OFDM signals when they are transmitted through a non-linear channel. The complex envelope of the OFDM signals are modeled as a complex proper gaussian random process and the channel non-linearity is characterized through a power series expansion of its AM/AM and AM/PM distortion curves. Using the Moment Theorem for complex gaussian random processes, closed form expressions for the autocorrelation function and the power spectrum density of the signal produced at the non-linear channel output are obtained. These expressions are applied to specific situations in which 1, 2 and 3 OFDM signals share the nonlinear channel, producing results that quantify the distortions corresponding to intermodulation products of different orders and the effect of varying the signal input back-off value.

Le travail présenté dans ce manuscrit a pour objet l’étude et le développement d’un banc de caractérisation généraliste appliqué à l’extraction du modèle comportemental d’ampliﬁcateur TPM-NIM (Two-Path Memory Nonlinear Integral). Ce modèle qui dispose d’une des architectures les plus abouties au laboratoire XLIM requiert une instrumentation microonde haut de gamme, très onéreuse, hors de portée de la majorité des concepteurs pour sa mise en œuvre expérimentale. L’objectif est donc de proposer des principes de mesure originaux permettant d’identiﬁer le modèle TPM-NIM avec une instrumentation standard. Dans ces travaux, deux bancs sont présentés : tout d’abord, un banc de caractérisation développé autour d’une instrumentation de pointe disposant des meilleures propriétés pour extraire le modèle. Puis, un banc construit autour d’une instrumentation standard mais incluant des méthodes de traitement et de mesure novatrices. Ces deux bancs ont été utilisés avec plusieurs véhicules de tests et il ressort que le second permet de diminuer le bruit des mesures de phase tout en réduisant le coût total des équipements. Enﬁn, une dernière partie est consacrée à la comparaison du modèle TPM-NIM avec deux modèles comportementaux classiques mettant en avant sa polyvalence.

The work presented in this manuscript is devoted to the study and development of a general characterization bench applied to the extraction of the TPM-NIM (Two-Path Memory Nonlinear Integral) ampliﬁer behavioral model. This model, has one of the most advanced architectures at the XLIM laboratory. It requires a high-end microwave instrumentation, overpriced and beyond reach for most of the designers for its experimental implementation. The aim is to propose some original measurements principles allowing the TPM-NIM model’s identiﬁcation with a standard instrumentation. Two benches are presented in these works : ﬁrstly, a characterization bench, developed using a high performance instrumentation with the best properties to extract the model. Then, a bench, built with a standard instrumentation but through innovative processing and measurement methods. These two benches have been used with several test vehicles and it appears that the second one decreases the noise of phase measurements while reducing the equipment’s total cost. Finally, a last part is dedicated to the comparison of the TPM-NIM model with two classic behavioral models by emphasizing its versatility.

Cette thèse porte sur l’identification de systèmes non linéaires représentables en séries de Volterra, et son application à des systèmes sonores. Les séries de Volterra, qui permettent de représenter une large classe de systèmes non linéaires, correspondent à un développement en série organisé par ordre d'homogénéité par rapport à l’entrée: chaque terme homogène est caractérisé par un noyau convolutif dont l’ensemble fournit une "signature complète" du système représenté. Les travaux présentés reposent sur le développement d’une étape préalable de séparation des termes de la série pour améliorer l’identification des noyaux de Volterra. Par rapport aux méthodes déjà existantes de séparation en ordres homogènes, basées sur des relations d’amplitudes entre signaux tests, l'approche adoptée dans cette thèse consiste à exploiter les relations de phase entre signaux afin d'obtenir une méthode robuste. Cela est tout d’abord obtenu de manière abstraite pour le cas de signaux d’excitations complexes. De cette idée, plusieurs méthodes adaptées au cas des signaux réels sont développées. Ceci amène à définir de nouvelles catégories de signaux pour décrire la sortie d’une série de Volterra, regroupant les contributions selon leurs propriétés de phase. Les méthodes de séparation proposées sont testées et appliquées à une pédale d’effet de guitare. Ensuite, des méthodes d’identification spécifiques aux nouveaux types de signaux sont présentées. Enfin, une méthode d’estimation des paramètres d’une représentation d’état à non-linéarités polynomiales est développée. Celle-ci est appliquée à un haut-parleur électrodynamique, dont les caractéristiques non linéaires sont étudiées.

This thesis addresses the identification of nonlinear systems that can be represented with Volterra series, and its application to audio systems. Volterra series give an input-output representation, approximated to within a given error, of any time-invariant continuous nonlinear system with fading memory. Technically, they correspond to a series expansion sorted by homogeneity order with respect to the input: each homogeneous term is characterized by a convolutive kernel whose set provides a "complete signature" of the modelled system. The works presented are based on the development of a preliminary step that consists in separating the series' terms to improve Volterra kernels' identification. Compared to existing homogeneous order separation methods, which are based on amplitude relationships between test signals, the approach chosen in this thesis is to exploit phase relationships between signals to obtain a robust method. This is first obtained in the theoretical case of complex excitation signals. From this idea, several methods suited to the use of real signals are developed. This leads to define new signals categories that describes the output of a Volterra series, sorting nonlinear contributions according to their phase properties. The proposed separation methods are applied and tested on a guitar pedal effect. Then, specific identification methods…

We have treated the polynomial optimization problem in abstract algebra allowing us algebraic freedom to transform polynomials. Unlike previous attempts where only a set of limited benchmarks have been used, we have focused on a class of polynomials called “Volterra series” with a wide range of applications in modeling nonlinear systems. We have exposed Volterra series characteristic, in which some inputs are delayed inputs, to store some of the products in these polynomials for the subsequent clock cycles. This results in replacement of multiplications with memory elements. In addition to variable factorization, we have also introduced factorization based on common coefficient divisors allowing us to expose more possible common subexpressions. These optimization have resulted in reduction of 41.0% and 12.9% in number of multiplication and addition respectively in comparison with common subexpression elimination technique used in compilers. At implementation level, instead of relying on conventional arithmetic operations, we have used redundant arithmetic to increase the speed of the polynomial evaluation. To avoid manual and tedious generation of such systems, we have developed a generator. This generator parses the polynomials into expression trees and automatically outputs Verilog HDL code. The generator uses interval arithmetic to find the minimum required bit-width in our evaluation of each variable. We have addressed the issues with truncation of redundant representation which unlike conventional arithmetic is not trivial. We have also used the non-uniform arrival time of operands in multi-operand addition to decrease the delay of adder trees. These improvements in implementation have resulted in 72.7% increase in the speed of synthesized circuit in comparison with the implementation based on conventional operators. Finally we have used our methods on an application from digital communication domain. We have implemented a digital pre-distorter to reverse the effect of non-linearity in a satellite communication channel modeled using Volterra series. We have compared our results with previous attempts which relied on hand-optimization of similar systems. Our optimization techniques have resulted in an increase of 55.9% in speed comparing to direct evaluation of Volterra series. When area optimization is the main objective, our approach has resulted in a decrease of 37.1% and 73.0% in number of DSP's and Adaptive Logic Modules (ALM) respectively.

Cette thèse porte sur la caractérisation de structures mécaniques, au travers de leurs paramètres structuraux, à partir d'observations perturbées par des bruits de mesure, supposés additifs blancs gaussiens et centrés. Pour cela, nous proposons d'utiliser des modèles à temps discret à parties linéaire et non-linéaire séparables. La première permet de retrouver les paramètres recherchés tandis que la seconde renseigne sur la non-linéarité présente. Dans le cadre d'une modélisation non-récursive par des séries de Volterra, nous présentons une approche à erreurs-dans-les-variables lorsque les variances des bruits ne sont pas connues ainsi qu'un algorithme adaptatif du type LMS nécessitant la connaissance de la variance du bruit d'entrée. Dans le cadre d'une modélisation par un modèle récursif polynomial, nous proposons deux méthodes à partir d'algorithmes évolutionnaires. La première inclut un protocole d'arrêt tenant compte de la variance du bruit de sortie. Dans la seconde, les fonctions fitness sont fondées sur des fonctions de corrélation dans lesquelles l'influence du bruit est supprimée ou compensée.

This PhD deals with the caracterisation of mechanical structures, by its structural parameters, when only noisy observations disturbed by additive measurement noises, assumed to be zero-mean white and Gaussian, are available. For this purpose, we suggest using discrete-time models with distinct linear and nonlinear parts. The first one allows the structural parameters to be retrieved whereas the second one gives information on the nonlinearity. When dealing with non-recursive Volterra series, we propose an errors-in-variables (EIV) method to jointly estimate the noise variances and the Volterra kernels. We also suggest a modified unbiased LMS algorithm to estimate the model parameters provided that the input-noise variance is known. When dealing with recursive polynomial model, we propose two methods using evolutionary algorithms. The first includes a stop protocol that takes into account the output-noise variance. In the second one, the fitness functions are based on correlation criteria in which the noise influence is removed or compensated.

La miniaturisation de circuits intégrés, les hautes fréquences de fonctionnement, la baisse des potentiels d'alimentation, les fortes densités d'intégration rendent les signaux numériques propagés sur les interconnexions très susceptibles à la dégradation voire à la corruption. En vue d’évaluer la compatibilité électromagnétique et l’intégrité du signal il est nécessaire de disposer dès les premières phases de développement de modèles précis de ces interconnexions pour les insérer dans les simulateurs temporels. Nos travaux s'inscrivent dans ce contexte et concernent plus particulièrement la modélisation comportementale des buffers et drivers de ligne de transmission. Ils ont abouti à une approche originale de modélisation notamment basée sur les séries de Volterra-Laguerre. Les modèles boites noires développés disposent d’une implémentation SPICE assez simple autorisant ainsi une très bonne portabilité. Ils sont faciles à identifier et disposent d’une complexité paramétrique permettant un gain important de temps de simulation vis-à-vis des modèles transistors des drivers. En outre les méthodes développées permettent une modélisation dynamique non linéaire plus précise du port de sortie, et une gestion plus générale des entrées autorisant notamment une très bonne prise en compte du régime de sur-cadencement ce que par exemple ne fait pas le standard IBIS.

Integrated circuits miniaturization, high operating frequencies, lower supply voltages, high-density integration make digital signals propagating on interconnects highly vulnerable to degradation. Assessing EMC and signal integrity in the early stages of the design flow requires accurate interconnect models allowing for efficient time-domain simulations. In this context, our work addressed the issue of behavioral modeling of transmission line buffers, and particularly that of drivers. The main result is an original modeling approach partially based on Volterra-Laguerre series. The black box models we developed have a fairly simple implementation in SPICE thus allowing a very good portability. They are easy to identify and have a parametric complexity allowing a large gain in simulation time with respect to transistor driver models. In addition, the developed methods allow a more accurate output port nonlinear dynamics modeling, and a more general management of inputs. A very good reproduction of driver behaviour in overclocking conditions provides a significant advantage over standard IBIS models.

Les systèmes de communication modernes convergent vers un fonctionnement multi-standard associé à des formats de modulation à fort PAPR où l’amplificateur de puissance doit être d’abord optimisé en rendement et où la linéarité sera corrigée ensuite par l’ajout d’un prédistorteur. Si cette solution semble fonctionnelle, elle parait inadaptée et peu efficace sur les systèmes 5G où les largeurs de bandes visées posent à la fois des problèmes d’architecture (complexité de la voie d’observation) etde précision des modèles comportementaux usuels basés sur une simplification de la série de Volterra dans sa forme discrète (GMP, DDR) face à des effets de mémoire exacerbés mais également d’efficacité énergétique du système linéarisé (DPD+PA). Il devient nécessaire dans ce contexte d’aller vers un modèle de prédistorteur moins dépendant des caractéristiques du signal à linéariser, notamment par le modèle TPM (Two path Memory) développé à XLIM, basé sur une simplification de la série de Volterra dans sa forme continue, s’avère indépendant des caractéristiques du signal à linéariser.Notre travail s’est attaché à évaluer les performances en linéarité des modèles classiques (GMP, DDR) et du modèle TPM sur différents amplificateurs de puissance, soit à partir de simulations ou à partir de mesures physiques du PA. Pour ce faire nous avons mis en place un environnement de simulation ainsi qu’un banc d’évaluation des modèles de prédistorsion avec le PA physique afin de quantifier les performances en ACPR suivant la variation de caractéristique du signal (puissance, fréquence, statistique). L’ensemble de ces expérimentations ont permis de vérifier d’une part la faible robustesse des approches classiques (GMP/DDR), d’autre part la stabilité des performances de l’approche TPM quel que soit le scenario envisagé. Cette étude ouvre donc la voie d’une nouvelle génération de prédistorteur qui, extrait une fois pour toute, ne nécessiterait qu’une mise à jour sur des phénomènes à dynamique lente (vieillissement) et permettrait d’envisager une architecture simplifiée de la voie d’observation du DPD ; donc une amélioration de l’efficacité énergétique globale du système linéarisé.

Modern communications systems converge towards multi-standard operation combined with high PAPR modulation formats where the power amplifier must first be optimized in efficiency and where linearity will then be corrected by adding a predistorter. If this solution seems functional, it seems inadequate and ineffective on 5G systems where the targeted bandwidths pose both architectural problems (complexity of the observation path) and problems of accuracy of the usual behavioural models based on a simplification of the Volterra series in its discrete form (GMP, DDR) in the face of exacerbated memory effects but also of energy efficiency of the linearized system (DPD+PA). In this context, it becomes necessary to move towards a predistorter model less dependent on the characteristics of the signal to be linearized, in particular by the TPM (Two path Memory) model developed…

The linearity and noise requirements in multi-band multi-standard applications make the design of RF CMOS mixers a very challenging task. In this dissertation two downconversion mixers based on the Gilbert-cell topology are proposed. Linearity and noise were the principal figures of merit for the proposed mixers. For linearity improvement, post distortion harmonic cancellation (PDHC) was employed. And, for noise reduction, dynamic current injection combined with an LC filter tuned at the LO frequency and thermal-noise cancellation were used. A Volterra series analysis of the transconductance stage is reported to show the effectiveness of the post-distortion harmonic cancellation technique. The added linearization circuitry does not increase the size of the mixer, nor does it degrade conversion gain, noise figure, or power consumption. Electrical simulations were performed on extracted layout level from the first topology and schematic level from the second topology. Using an IBM 0.13 mm CMOS process improvements on IIP3 and IIP2 in comparison to the conventional Gilbert-cell mixer are demonstrated. For the first topology, we achieved a conversion gain of 10.2 dB with a NF of 12 dB for the designed mixer working at 2 GHz, with a low-IF of 500 kHz and an IIP2 and IIP3 of 55 dBm and 10.9 dBm, respectively, while consuming only 5.3 mW from a 1.2 V supply. For the second topology, we achieved a conversion gain range of [13.8 ~11] dB, an input reflection coefficient (S11) of [-18 ~-9.5] dB and a NF of [8.5 ~11] dB in the frequency range of 1 to 6 GHz. For the linearity specs, an IIP3 of 0 dBm was achieved for the whole frequency range, while consuming 19.3 mW from a 1.2 V supply, making the second topology well suited for multi-band and multi-standard operation.

Os requisitos de linearidade e ruído em aplicações multi-banda e multi-protocolo fazem que o projeto de misturadores RF seja uma tarefa muito desafiadora. Nesta dissertação dois misturadores com base na topologia célula de Gilbert são propostas. Linearidade e ruído foram as principais figuras de mérito consideradas para o misturadores propostos. Para aumento linearidade, foi utilizada uma técnica de cancelamento de harmônicas pós-distorção (PDHC). E, para redução de ruído, foi utilizado um circuito de redução dinâmica de corrente combinada com um filtro LC sintonizado na frequência do LO e cancelamento de ruído térmico. A análise por séries Volterra do estágio transcondutância do misturador proposto é reportada para mostrar a eficácia da técnica de cancelamento de harmônicos com pósdistorção. O circuito de linearização adicionado não aumenta o tamanho do misturador, nem degrada ganho de conversão, figura de ruído, ou consumo de potência. Simulações elétricas foram realizadas em nível de pós-layout para a primeira topologia e nível esquemático para a segunda topologia, usando processo CMOS de 0.13 mm da IBM. As melhorias em IIP2 e IIP3 são apresentadas em comparação com o misturador do tipo célula de Gilbert convencional. Para a primeira topologia, foi obtido um…

▼ In radio frequency (RF), filtering is an essential part of RF transceivers. They are employed for different purposes of band selection, channel selection, interference cancellation, image rejection, etc. These are all translated in selecting the wanted signal while mitigating the rest. This can be performed by either selecting the desired frequency range by a band pass filter or rejecting the unwanted part by a band stop filter. Although there has been tremendous effort to design RF tunable filters, there is still lack of designs with frequency and bandwidth software-tuning capability at frequencies above 4 GHz. This prevents the implementation of Software Defined Radios (SDR) where software tuning is a critical part in supporting multiple standards and frequency bands. Designing a tunable integrated filter will not only assist in realization of SDR, but it also causes an enormous shrinkage in the size of the circuit by replacing the current bulky off-chip filters. The main purpose of this research is to design integrated band pass and band stop filters aimed to perform interference cancellation. In order to do so, two systems are proposed for this thesis. The first system is a band pass filter capable of frequency and band with tuning for C band frequency range (4-8 GHz) and is implemented in 0.13 µm BiCMOS technology. Frequency tunability is accomplished by using a variable capacitor (varactor) and bandwidth tuning is carried out by employing a negative transconductance cell to compensate for the loss of the elements. Additional circuitry is added to the band pass filter to enhance the selectivity of the filter. The second system is a band stop filter (notch) with the same capability as the band pass filter in terms of tuning. This system is implemented in C band, similar to its band stop counterpart and is capable of tuning its depth by using a negative transconductance in an LC tank. A negative feedback is added to the circuit to improve the bandwidth. While implemented in the same process as the band pass filter, it only employs CMOS transistors since it is generally more attractive due to its lower cost and scalability. Both of the systems mentioned use a varactor for changing the center frequency which is a nonlinear element. Therefore, the nonlinearity of it is modelled using two different methods of nonlinear feedback and Volterra series in order to gain further understanding of the nonlinear process taking place in the LC tank. After the validation of the models proposed using Cadence Virtuoso simulator, two methods of design and tuning are suggested to improve the linearity of the system. After post layout-extraction, the band pass filter is capable of Q tuning in the range of 3 to 270 and higher. With the noise figure of 10 to 14 dB and input 1-dB compression point as high as 2 dBm, the system shows a reasonably good performance along its operating frequency of 4 to 8 GHz. The band stop filter which is designed in the same frequency band can achieve better than 55 dB of rejection with the noise… Advisors/Committee Members: Ha, Dong Sam (committeechair), Lester, Luke F.
