▼ All electronic systems have inherent noise sources and a certain percentage of energy radiating from the system. The distorted differential signal in a communication link generates an unwanted common-mode (CM) component more severely at the backplane connector at twice the Nyquist frequency or at data rate frequency and harmonics (F_dr). The CM components are eventually radiated by the PCB parasitic antennas and degrade electromagnetic compatibility (EMC) performance. Regulatory bodies, for instance the Federal Communication Commission (FCC) and International Special Committee on Radio Interference (CISPR), prescribe a limit to control maximum radiation. It is therefore essential for systems-on-chip (SOCs) with high-performance digital large-scale integration (LSI) and RF/analog circuits to have less electromagnetic radiation and to minimize electromagnetic interference (EMI) inside active devices. Meeting these guidelines becomes more challenging at high speed, as higher frequencies radiate more efficiently through small openings. Therefore, EMI is a challenging issue for packaging and PCB design at high speed. The EMI issue usually comes up late in the system, around the developmental stage, and requires a costly solution that is difficult to implement. Therefore, it is essential to counter the EMI issue during the product design phase instead of handling it at the end of product development. In this thesis, EMI-related common-mode noise is investigated in three stages: (1) identification of CM noise sources, (2) analysis and prediction of CM noise of the output driver and parallel I/Os and (3) suppression of CM noise. In the first stage, the predominant source of CM noise is identified by a simplified communication link model, which only considers the non-idealities of the signal source and passive link. The signal source is an output of a high-speed serializer/deserializer (SERDES) transmitter (Tx), and the passive link is comprised of packaging and PCB interconnections. The CM voltage spectrum profile is categorized into two types of distortions, namely, linear distortion and non-linear distortion. The linear distortion is produced by skew, loading and amplitude mismatch between P/N channels, whereas the rising/falling edge mismatch is categorized as non-linear distortion since it produces a large power component at F_dr, causing a radiation issue and degrading the EMC performance. Analysis reveals that the non-linear active circuit predominantly produces the asymmetric rise and fall time of the output signal and is an intrinsic source responsible for generating the CM noise. In the second stage, we present a novel methodology to systematically analyze and predict the CM noise of an output driver from various dependent parameters, including CMOS process corners, input signal, power supply and passive interconnections. Comprehensive analysis and prediction of EMI-related CM noise for a 20-Gb/s output driver in a 65-nm CMOS process is presented. Due to the NMOS-PMOS configuration in the…

Thesis Ph. D. Michigan State University. Mechanical Engineering 2016

"In this work we consider several nonlinearity-based and/or noise-related phenomena that were observed recently in micro-electromechanical resonators. The main goal here is to closely examine these phenomena, understand their underlying fundamental physics, and find ways to employ them for measurement purposes and/or to improve the performance of specific classes of micro-electromechanical systems (MEMS). The general perspective of this work is based on the acceptance of the fact that nonlinearity and noise represent integral parts of the models for these systems, and the discussion is constructed about the cases where these generally "undesirable" features can be utilized rather than avoided. In this dissertation we consider three different, but related, topics. To start, we analyze the stationary probability distribution of a nonlinear resonator driven by Poisson noise at a non-zero temperature of the environment. We show that Poisson pulses with low pulse rates cause the power-law divergence of the probability density at the resonator equilibrium in the rotating frame both in overdamped and underdamped regimes. We have also found that the shape of the probability distribution away from the equilibrium position is qualitatively different for overdamped and underdamped cases. In particular, in the overdamped regime, the form of the secondary singularity in the probability distribution strongly depends on the reference phase of the resonator response as well as the pulse modulation phase, while in the underdamped regime there are several singular peaks, and their location is determined by the resonator decay rate in the rotating frame. Finally, we show that even weak Gaussian noise affects the probability distribution by smoothing it in the vicinity of singular peaks. Second, we discuss a time-domain technique for characterizing parameters for models of a single vibrational mode of symmetric micromechanical resonators, including coefficients of conservative and dissipative nonlinearities as well as the strengths of noise sources acting on the mode of interest. These nonlinearities result in an amplitude-dependent frequency and a non-exponential decay, while noise sources cause fluctuations in the resonator amplitude and phase. We capture these features in the modal ringdown response. Analysis of the amplitude of the ringdown response allows one to estimate the quality factor and the dissipative nonlinearity, and the zero-crossing points in the ringdown measurement can be used for characterization of the linear natural frequency and the Duffing and quintic nonlinearities of the vibrational mode which arise from a combination of mechanical and electrostatic effects. Additionally, we show that statistical analysis of the zero-crossing points in the resonator response allows us to separate effects of additive, multiplicative, and measurement noises and estimate their corresponding intensities. Finally, we examine the problem of self-induced…

Thesis Ph. D. Michigan State University. Mechanical Engineering Physics 2012.

In this work we examine several noise-induced phenomena that are found in nano- and micro-electromechanical systems. Our aim is to exploit these phenomena, where possible, for system identification and sensing applications. The exception being our discussion of nonlinear oscillators, where our goal is to remove the effect of noise as much as possible. In general, however, our viewpoint is one of embracing the noise and nonlinearity that are an inevitable part of miniaturization and seek new modes of micro- and nano-system operation applicable where noise and nonlinearity are fundamentally unavoidable.In this work we discuss three different, but related, topics. First, we discuss the dynamics of a system subject to a parameter sweep through a bifurcation in the pres- ence of noise. We develop approximate distributions for the time at which a system swept through a subcritical pitchfork or a saddle-node bifurcation will leave the local region of phase space, leading to a sudden jump in response amplitude. These distri- butions are developed in the limit of "fast" sweeping, where the sweep rate is large compared to the noise strength, which is relevant to most MEMS applications. We then present the results of sweeping experiments performed on a MEMS resonator and show the value of our analytic predictions. Our primary conclusion is that de- layed bifurcation is prominent in MEMS devices, and we provide predictive tools for predicting the resulting distribution of jump events.Next, we consider a novel dynamical bridge sensing paradigm. This sensing methodology employs a vibrating bistable system arranged, by tuning of parameters, such that the rate of noise-activated escape out of the two stable basins of attraction are identical. The ratio of occupation probabilities can become extremely sensitive atthis point when the noise is weak. We calculate the sensitivity and detection time of the balanced dynamical bridge for use as a general use detector and we develop the conditions required and demonstrate its application as a detector of non-Gaussian noise. We illustrate the measurement of the parameters of a shot-noise process using a one-dimensional bridge model.Finally, we discuss phase noise in oscillators employing nonlinear frequency selec- tive elements. We employ the method of averaging to develop an expression for the spectrum of fractional frequency fluctuations in an oscillator. The expression for the spectrum of frequency fluctuations is quite general, although it neglects dynamics in the feedback elements of the oscillator. The expression contains elements of the noise model and the nominal limit cycle shape of the oscillator. We demonstrate the utility of the results by exploring the parameter space of a prototypical oscillator modeled by a biased Duffing equation. We find that one can reduce the phase diffusion con- stant of the oscillator by tuning the system to a zero-dispersion point of the resonator element, thus eliminating…

▼ Due to the rapid growth of the data traffic and the integration density of systems, the electromagnetic compatibility (EMC) of communication circuits is increasingly challenging to accomplish. In modern data centers, thousands of paralleled backplane communication links enable the tremendous volume of data throughput. However, these backplane links also generate undesired electromagnetic interference (EMI), which can potentially cause system malfunction. In a typical backplane communication link, differential non-return-to-zero (NRZ) signaling has been widely used for years. However, non-linear distortion of differential NRZ signals leads to a large common-mode (CM) noise at the double Nyquist frequency, which is a primary source of EMI. Therefore, the first half of the thesis focuses on investigating the CM noise of NRZ signals to understand the EMI issue in high-speed backplane links. Similar to the NRZ signaling, 4-level pulse amplitude modulation (PAM-4), which is the key solution for the next generation of 200/400 GbE communications, also suffers from the similar EMI problems. Hence, the second half of the thesis focuses on the EMI-related CM noise of PAM-4 signals. In the first half, the analysis of EMI-related CM noise of differential NRZ signals is presented from a circuit design perspective. A current-mode logic (CML) driver circuit is used for analysis and simulations. It is observed that the CM noise is correlated with the data rate, amplitude, and mismatch of rising and falling edges. Accordingly, a method for EMI reduction is proposed by optimizing the signal swing and the biasing voltage of the circuit. The proposed method is experimentally verified on a test chip fabricated in a 65 nm CMOS process. In the second half, the analysis of PAM-4 signals is presented, showing a correlation between the EMI-related CM noise and the system architecture. It is observed that the CM noise of a PAM-4 transmitter with a thermometer-coded architecture is intrinsically lower than the CM noise of a transmitter with a typical binary-scaled architecture. Hence, a mathematical expression is derived to estimate the CM noise of the PAM-4/8/16 signals, and transistor-level simulations in a 65 nm CMOS process are performed to further evaluate the correlation between the CM noise and the system architecture.

La machine asynchrone est à ce jour la référence dans les moteurs de traction ferroviaire. De nombreuses contraintes dictées par des normes notamment au niveau du bruit acoustique poussent l’industrie à développer des moteurs plus silencieux. Le vrillage connu pour réduire les ondulations de couple semble apporter également une réelle solution afin de diminuer les vibrations et le bruit émis par la machine. C’est dans ce contexte que ce projet en collaboration avec Alstom-Transport situé à Ornans et le soutien de MEDEE (pôle régional sur la maitrise énergétique) est réalisé. Cette thèse se focalise plus particulièrement sur le calcul des forces électromagnétiques dans l’entrefer à l’origine des vibrations, du bruit et du couple. Des modèles analytiques et à éléments finis estimant les forces électromagnétiques et intégrant le vrillage sont présentés et confrontés à des mesures expérimentales de vibration, de bruit et de couple. Les modèles utilisés sont valables pour les machines asynchrones à cage d’écureuil mais sont facilement adaptables pour les machines synchrones. Ils permettent de comprendre l’origine des forces électromagnétiques responsables du bruit et de trouver des configurations de machines moins bruyantes en jouant sur divers paramètres tels que : le vrillage, mais aussi le nombre de paires de pôles, le nombre d’encoches au stator et au rotor, la forme des encoches, la distribution du bobinage, etc.

The induction machine is the reference in railway traction motors. Numerous constraints dictated by standards, particularly regarding acoustic noise, are driving the industry to develop quieter engines. The skewing known to reduce torque ripples seems to also provide a real solution to reduce vibration and noise emitted by the machine. In this context, the project is realized in collaboration with Alstom-Transport located in Ornans with the support of MEDEE (regional pole on energy control). This thesis focuses on the calculation of magnetic forces in the air gap which originate vibration, noise and torque. Analytical and finite element models, which estimate electromagnetic forces and integrate skewing, are presented and compared with experimental measurements of vibration, noise and torque. The models used are valid for the squirrel-cage induction machines but are easily adaptable for synchronous machines. This allows one to understand the origin of the electromagnetic forces responsible for the noise, and to find configurations of less noisy machines. Various parameters such as skewing can be modified to reach this goal, as well as the number of pole pairs, the stator and rotor teeth number, the slot shape, the winding distribution, and so on.

Le réseau électrique s'utilise aujourd'hui comme support de transmission des signaux Ethernet. C’est le concept des courants porteurs en ligne. Cette technique de transmission permet d’obtenir des débits supérieurs au Wifi. Cependant, la complexité des réseaux électriques et l'environnement électromagnétique domestique peuvent dégrader les performances de cette technologie. L’environnement électrique de l'habitat avec ses appareils électroménagers divers en font un milieu difficilement maitrisable. L’objectif est d’appréhender et de modéliser cet environnement et le comportement des équipements qui y sont déployés. Pour cela, ce mémoire présente plusieurs méthodes pour modéliser les lignes électriques dans l'habitat. Les modélisations existantes sont difficilement généralisables à un réseau électrique quelconque. Nous proposons une modélisation de type circuit électrique.Son intérêt réside dans la simplicité de l'outil de simulation d'un réseau électrique, réalisé parla mise en cascade de plusieurs blocs intégrés à la librairie SPICE. Les blocs SPICE proposés prennent en compte la dépendance fréquentielle des paramètres des quadripôles. Une étape de caractérisation expérimentale est développée pour implémenter ces blocs. Un réseau expérimental de test, constitué de différentes technologies de câble, a été caractérisé en termes de bruit, d'impédance et de pertes d'insertion. Le rayonnement émis lors d'une transmission CPL a également été mesuré.

The power line grid is used for data transmission by means of the broad band powerline communication systems (BPLC) The main advantage of this technology consists in providing an existing infrastructure of wires and wall sockets that are easy to access throughout a building and offering physical data rates comparable with other existing communication technologies such as Wi-Fi. Nevertheless, the power line grid complexity, the various connected household appliances and the housing electromagnetic environment,impact the PLC transmission performances. As results the housing environment is not a controllable medium. The objective of the current thesis is to study the electromagnetic environment of the Indoor power line network, and to model the potential impacts of both the power line grid topology and the household devices on the PLC physical layer. The existing modeling approaches require a deduction of theirs parameters from the measurements and cannot be generally applied. We propose a new model based on circuitry approach. Its main interest consists in the simplicity of the simulation tool of power line grid which is based on series symmetric SPICE circuit integrated to SPICE library. To this aim, the characterization of the power cable, of the electrical accessories and household devices is necessary. The impedance of powered household devices is measured according to simple measurement protocol. The proposed model takes into account the variation of the whole primary parameters of the electrical cable as function of frequency. An experimental characterizationof the so…

▼ Power factor correction (PFC) converter is a species of switching mode power supply (SMPS) which is widely used in offline frond-end converter for the distributed power systems to reduce the grid harmonic distortion. With the fast development of information technology and multi-media systems, high frequency PFC power supplies for servers, desktops, laptops and flat-panel TVs, etc. are required for more efficient power delivery within limited spaces. Therefore the critical conduction mode (CRM) PFC converter has been becoming more and more popular for these information technology applications due to its advantages in inherent zero-voltage soft switching (ZVS) and negligible diode reverse recovery. With the emerging of the high voltage GaN devices, the goal of achieving soft switching for high frequency PFC converters is the top priority and the trend of adopting the CRM PFC converter is becoming clearer. However, there is the stringent electromagnetic interference (EMI) regulation worldwide. For the CRM PFC converter, there are several challenges on meeting the EMI standards. First, for the CRM PFC converter, the switching frequency is variable during the half line cycle and has very wide range dependent on the AC line RMS voltage and the load, which makes it unlike the traditional constant-frequency PFC converter and therefore the knowledge and experience of the EMI characteristics for the traditional constant-frequency PFC converter cannot be directly applied to the CRM PFC converter. Second, for the CRM PFC converter, the switching frequency is also dependent on the inductance of the boost inductor. It means the EMI spectrum of the CRM PFC converter is tightly related the boost inductor selection during the design of the PFC power stage. Therefore, unlike the traditional constant-frequency PFC converter, the selection of the boost inductor is also part of the EMI filter design process and EMI filter optimization should begin at the same time when the power stage design starts. Third, since the EMI filter optimization needs to begin before the proto-type of the CRM PFC converter is completed, the traditional EMI-measurement based EMI filter design will become much more complex and time-consuming if it is applied to the CRM PFC converter. Therefore, a new methodology must be developed to evaluate the EMI performance of the CRM PFC converter, help to simplify the process of the EMI filter design and achieve the EMI filter optimization. To overcome these challenges, a novel mathematical analysis method for variable frequency PFC converter is thus proposed in this dissertation. Based on the mathematical analysis, the quasi-peak EMI noise, which is specifically required in most EMI regulation standards, is investigated and accurately predicted for the first time. A complete approximate model is derived to predict the quasi-peak DM EMI noise for the CRM PFC converter. Experiments are carried out to verify the validity of the prediction. Based on the DM EMI noise prediction, worst case analysis is carried out and the… Advisors/Committee Members: Lee, Fred C.

▼ Accurate assessment of the electromagnetic excitation forces and the vibration behaviour of stators is essential to arrive at a suitable design for quiet operation of an electrical machine. These electromagnetic forces are produced on the surfaces of the stator and rotor along the air-gap periphery. The physical mechanisms underlying the production of the electromagnetic forces, and the characteristics of the ensuing vibrations are described in this thesis. In this thesis, comprehensive analytical methods are developed for the determination of the radial electromagnetic forces in squirrel-cage and wound-rotor induction machines. Various magnetic fields are generated due to the distribution of the windings in slots, the slotting of the stator and rotor surfaces, and the magnetic saturation of the iron. The air-gap fields are determined using the permeance method by expressing the MMF and the air-gap permeance as waves. In the analyses, the mutual interactions between the stator and rotor are incorporated. Asthe load increases, these interactions become prominent and influence significantly the nature of the air-gap field. Their effects on the electromagnetic forces are discussed from the perspective of the production of vibrations. Extensive investigations were conducted on a 7.5 kW squirrel-cage induction motor and a 70 kW wound-rotor induction motor to verify the validity of the analyses. The comparisons made between the experimental and the analytical results prove the general validity of the analytical methods. Conclusions are drawn with a view to determine the actual role played by the harmonic air-gap fields on the production of the electromagnetic forces and the ensuing vibrations. In the course of these investigations, an experimental set-up which is particularly suited for the measurement of magnetic fields, magnetic forces, resonant frequencies, vibrations and noise was developed. A fundamental study on the vibration behaviour of electrical machine stators using an experimental modal-analysis is presented in the thesis. Modal-analysis is a process of forcing a structure to vibrate predominantly at a selected resonance. In order to achieve this, distributed electromagnetic forces are used.Detailed investigations were conducted on the stator models of a 120 hp induction motor to study their vibration behaviour, and to critically examine the damping present in them. The physical interpretations of the results given in the thesis would help in acquiring a better understanding of the vibration behaviour of stators in relation to the problem of electromagnetic acoustic noise in electrical machines.

▼ Our recently developed MBE-grown ZnSSe-based visible-blind UV detectors can offer numerous applications in industry, scientific research as well as a number of commercial products. However, the noise characteristics and detectivity of these detectors, which reflect their ultimate limit on small-signal detection, has not been studied prior to this study. This work started with the construction of a hardware system for achieving noise characterization with high sensitivity, followed by a thoughtful study of the noise characteristics and detectivity of a group of ZnS0.58Se0.42 detectors. In total 27 detectors were selected from different locations of a 2-inch MBE-grown Schottky barrier structure fabricated on a GaP (100) wafer. The results of low frequency noise measurements reveal that these detectors can be classified into three different groups based on their different noise power spectrum: Group-A consists of 16 devices all show noise level below the background level of the detection system (about 10-26 A2/Hz) even at -12V; Group-B consists of 6 devices with detectable noise at reverse bias at or larger than 6V; Group-C consists of 5 devices with detectable noise even at -3V. We attribute this non-unifomity to the different damage level caused by wire bonding process. One typical detector from each of the three groups was selected for further detailed studies. The responsivity measurement shows that they all have the cut-off wavelength at about 400nm with very good rejection power for longer wavelength. The responsivity in the UV spectral range is around 0.1A/W. The impulse response measurements indicate that spectral range is around 0.1A/W. The impulse response measurements indicate that the detectors have a response time around 1.4ns and this value is basically unchanged from 0 to -12V. The bandwidth of the diodes was found to be about 300MHz by applying Fourier transformation on the measured impulse response spectra. The I-V characteristics of these detectors were measured for extracting various parameters for the determination of the shot noise power. Finally, the total noise power of these detectors were evaluated, and the best values of noise equivalent power and specific detectivity are calculated to be 2.8 x 10-11W and 1.7 x 1011 mHz1/2W-1, respectively. These values are among the best reported so far from both II-VI and GaN-based Schottky UV diodes and also about two orders of magnitude better than the best value provided from commercial products of Si photodiodes. These results indicate that ZnSSe photodetectors are highly promising for visible-blind UV detection applications requiring extremely high detectivity.

Le XXe siècle a marqué le succès de la construction du modèle standard de la physique des particules. Elaborée entre les années 1930 et 1970, cette théorie des particules élémentaires et des interactions électromagnétique, faible et forte a depuis été abondamment vérifiée auprès des collisionneurs tels que le LEP et le Tevatron. Malgré ce succès, certaines questions laissées en supsens ont nécessité l'élaboration de nouvelles théories permettant de dépasser le cadre du modèle standard. Parmi ces théories nombreuses sont celles prédisant l'existance d'un nouveau boson Z' à l'échelle du TeV. Les données du LHC, recueillies depuis son démarrage à l'automne 2008, offrent une nouvelle fois l'opportunité de confronter le modèle standard à ses prédictions et de rechercher les signatures de l'existence de nouvelle physique jusqu'à des énergies inégalées. Le travail mené au sein de l'expérience ATLAS au cours de ces quatres premières années s'est ainsi orienté autour de la compréhension du détecteur et de l'analyse des premières données. Cette thèse couvre ces deux aspects. La première partie du travail présenté revient ainsi sur la mise en évidence d'une pathologie de l'électronique de lecture du calorimètre à argon liquide d'ATLAS ainsi que sur l'étude de larges déviations cohérentes du bruit observées depuis sa mise en service. La mise en place d'une stratégie de préservation des données collectées y est détaillée. La seconde partie de ce manuscrit se concentre sur la recherche d'un nouveau boson Z'. Si tant est qu'une telle particule existe, sa décroissance en un électron et un positron devrait donner lieu à l'apparition d'une nouvelle résonance massive dans le spectre en masse invariante diélectron. Les performances de reconstruction et d'identification des électrons, particulièrement à haute impulsion transverse, sont étudiées. L'analyse des 4.9 fb-1 de données collectées en 2011 est décrite. En l'absence de déviation significative par rapport aux prédictions du modèle standard, le spectre en masse invariante diélectron est réinterprété afin de dériver les limites sur l'existence de nouveaux bosons issus de théories de grande unification (E6) et sur l'existence d'un boson de type SSM. Ces limites et celles obtenues par l'expérience CMS sont à l'heure actuelle les plus contraignantes quant à l'existence de ces nouveaux bosons.

The Standard Model of particle physics has known a tremendous rise during the twentieth century. Built up, from the early 1930s to the 1970s, this theory describing elementary particles and their interactions (electromagnetic, weak, strong) has now been intensivly tested by LEP and Tevatron colliders. Besides its succes, some problems remain and have lead to new theories attempting to go beyond the standard model. Many of them are predicting the existence of a new gauge boson Z', which is supposed to be observed at the TeV scale. Data recorded by the LHC since automn 2008 are a new opportunity to check the consistency of the Standard Model and to search for new physics evidence. Work that has…

Le travail réalisé lors de cette thèse s’inscrit dans le projet de création d’un calorimètre électromagnétique pour le futur International Linear Collider (ILC) au sein de la collaboration CALICE. Le calorimètre est dit ultra-granulaire du fait du grand nombre de pixels de détection : environ 82 millions dans le calorimètre final complet. C’est ce nombre élevé de détecteurs à lire qui a conduit au développement de circuits intégrés dédiés à cette tâche, l’usage d’électronique classique n’étant pas possible dans ce cas du fait de contraintes dimensionnelles. Les travaux démarrent par l’étude de la puce SKIROC2, développée par le laboratoire Omega, qui est l’état de l’art de l’ASIC de lecture pour ce projet. Les performances sur carte de test et dans l’environnement du détecteur ont été mesurées, ce qui a permis de tirer certaines conclusions sur les forces et les faiblesses de SKIROC2. Après cette étude, le travail a été le développement d’un nouvel ASIC de lecture se basant sur SKIROC2. L’objectif étant de préserver les forces de SKIROC2 tout en tentant d’en corriger les faiblesses. Le nouvel ASIC a été conçu dans une technologie tout juste disponible au moment de la conception. Il a donc tout fallu redessiner en repartant de zéro. Il s’agit en cela de building blocks plus que d’un véritable ASIC de lecture. Trois structures de préamplificateurs de charge ont été testées, l’architecture générale et le fonctionnement d’un canal de lecture étant largement inspirés de SKIROC2.

This work takes place in the design project of the electromagnetic calorimeter for the future International Linear Collider (ILC) within the CALICE collaboration. The final calorimeter will be made of 82 million of PIN diodes; this is where the term “high granularity” comes from. The need for a read-out ASIC is a consequence of this high number of detectors, knowing that the dimensions of the electromagnetic calorimeter are a big constraint: the standard electronics is not an option. This work starts from an existing ASIC called SKIROC2. This state-of-the-art read-out chip has been designed by the Omega laboratory, a member of the CALICE collaboration. The performances on testboard and in the detector environment have been measured. It allowed to conclude on the advantages and drawbacks of using SKIROC2 in the calorimeter. After that the focus has been made on the design of a new read-out chip based on SKIROC2. The main goal was to preserve the good performances of SKIROC2 while trying to correct the encountered issues. This new ASIC has been developped in a newly released technology available during the design phase. Therefore the design has been started from scratch. The final chip is composed of building blocks rather than a ready-to-use read-out chip. Three charge preamplifier designs have been tested, the general architecture of a read-out channel being largely inspired by SKIROC2.

▼ Instrumentation in a nuclear power plant is critical in monitoring the stability and safety levels of a reactor. Temperature is a key measurement performed on the core of a reactor to control the power output and sustain a safe thermal margin. If there is a dramatic change in temperature, failure is likely to follow if action is not taken to cool the system. Traditionally, to measure the temperature of a reactor, several resistance temperature detectors are placed in predefined locations on the system. Resistance temperature detectors (RTD) are typically platinum coiled wire wrapped around a ceramic cylinder and encased in a metal sheath. Due to the harsh environment of nuclear reactors, the RTDs degrade and their resistance measurements drift over time. This drift in resistance can be misunderstood as a drift in reactor temperature. In the past, the RTDs would be serviced every few years either through calibration or replacement. To service the RTDs the reactor is shut down and a person is sent into a dangerous environment. Utilizing Johnson Noise Thermometry (JNT) will reduce the occurrences of service needed for RTDs and provide a high- accuracy temperature measurement. JNT is a first order fundamental expression of temperature invulnerable to drift in the RTD’s physical condition. The signal processing behind JNT is presented in the following document. Spectral Estimation methods are utilized in order to remove electromagnetic interference (EMI) from the JNT measurement. These methods are unique to this dissertation. The EMI estimation method is modeled and simulation results are presented. The modeling of the EMI estimation involves locating EMI, analysis of EMI effects, and removal without bias. Finally, results from numerical and experimental verification are presented. The research presented here is important to furthering the future of the nuclear industry for several reasons. With this technology applied to existing systems reactor shut-down time can be decreased, technicians limit their exposure to dangerous radiation zones, and financial support for lengthy shut-downs is saved. The instrumentation community will benefit through the innovation of signal processing for very small signal versus noise interference.

▼ Stochastic drift noise sources that usually arise from coupling with the external environment limit the resolution of the Canterbury He:Ne ring-laser gyroscopes as rotation sensors. The characterisation of such stochastic drifts is discussed along with effects that bring about the coupling between the environment and the gyroscope output. Techniques which may be employed to minimise the coupling are also investigated. The optimal He:Ne gas pressure with respect to the requirement that output power be maximised while retaining single longitudinal mode operation is investigated. In addition to the empirical optimisation of gas pressure the mechanisms that lead to the reported observations are discussed. In particular it is proposed that radiation trapping plays an important role in determining the optimum fill pressure. The effects of the gain medium when the optical powers of the counter-propagating beams are unequal is analysed in the context of the third-order theory of the laser. With appropriate approximations a dominant term is found that heavily influences frequency pushing and pulling in the 4m perimeter high-Q gyroscope C-II. Experimental results are in good agreement with the theoretical predictions in the cases where the assumptions of the theory are valid. Long-term drift sources are analysed and described by the fractional Brownian motion (fBm) model. The impact of this drift process on the resolution of the gyroscope is investigated. The relationship between the quantum limited white frequency noise clue to spontaneous emission and the fBm drift noise is of particular interest since it defines the averaging time that produces the best resolution of the rotation rate measured in terms of the beat frequency between the counter-propagating beams of the gyroscope. The optical frequency stabilisation of c-II is described and analysed. The method employed is somewhat different from traditional stabilisation schemes because the laser possesses very low output powers due to extremely high reflection mirrors. The applicability of traditional stabilisation schemes to a low power ( ~ 10 p vV) laser such as c- II, is discussed. An experimental investigation of injected coloured noise in the ring-laser gyroscope is reported. In particular the probability distribution of the steady-state phase difference between the counter-propagating waves of a locked ring-laser gyroscope is measured for various noise inputs. The results are found to be in good agreement with previous theoretical predictions.
