1. Pham, Hao Qui. Intergration of a dynamic offset testbench to measure comparator offsets in 0.18um CMOS.

Degree: MS, Electrical and Electronic Engineering, 2020, California State University – Sacramento

High-speed latching comparators are important building blocks in analog and mixed-signal integrated circuits (ICs) such as analog-to-digital converters. A key performance parameter of these comparators is the input offset voltage. A simulation technique called the dynamic offset test bench (DOTB) is used to obtain the input offset voltage during the design process. In simulations, a transistor-level design of the comparator to be fabricated is connected to the DOTB. The DOTB is used in simulations comprises idealized virtual components and therefore cannot be fabricated. This project comprises the transistor-level design and simulation of a DOTB for fabrication in a particular IC design process. The eventual goal is to use a DOTB to test real comparators (i.e., comparators in silicon rather than in simulations). The data gathered can be used to create more accurate models of comparator performance. Important performance aspects of the silicon DOTB have been determined from simulations and indicate that it is practical to construct and will be useful for testing. Simulations testing the DOTB performance have been performed across process, supply voltage, and temperature (PVT) variations. An issue that could affect accuracy has been detected, and the mechanism causing it has been identified. Advisors/Committee Members: Heedley, Perry L..

Subjects/Keywords: Input referred offset voltage of comparator; Top-level DOTB design and simulations; Fully-differential DOTB

2. Bommireddipalli, Aditya Vighnesh Ramakanth. Design of a Precision Low Voltage Resistor Multiplying Digital-to-Analog Converter.

Degree: MS, Electrical Engineering, 2017, Texas A&M University

This work aims to model the effect of the input offset voltage of an operational amplifier on the performance of a high-precision, voltage-mode, resistor-based multiplying digital-to-analog converter (M-DAC). Based on the model, a high precision current buffer is proposed to isolate the resistor ladder from the operational amplifier. A 14-bit M-DAC operating with a ±1V reference of the proposed architecture. Post-layout simulations show that the proposed architecture reduces the offset voltage to an offset error in the DAC transfer function. The maximum DNL is maintained at -0.385 LSB for an input offset voltage of up to 60mV (1024 LSB). The current buffer also introduces an inversion of the output voltage, yielding a non-inverted output. This alleviates the need for an additional high precision op-amp to invert the output voltage.
