A new approach to oversampled delta-sigma A/D converters ( AZ modulators ) is introduced, where a differential pseudo-Npath filter stage is used as a basic cell. In this band-pass application, the z to -zN transformation ...

This thesis describes circuit architectures and techniques that facilitate the automatic synthesis and fabrication of analog-to-digital converters (ADCs). Since automated synthesis already exists for digital circuits a ...

Analog-to-digital converters (ADCs) convert analog continuous time signals into discrete time, digital format. One precondition that must be met for conventional nyquist rate ADCs is that the input signal must be suit ...

Delta-sigma modulators are currently a very popular technique for making high-resolution analog-to-digital and digital-to-analog converters. These oversampled data converters have several advantages over conventional N ...

The transition from second-generation (2G) to third-generation (3G) wireless cellular and cordless telephone systems requires multi-standard adaptability in a single RF receiver equipment. An important answer to this r ...

Advances in electronic systems have lead to the demand for high resolution, high bandwidth Analog-to-Digital Converters (ADCs). Oversampled ADCs are well- known for high accuracy applications since they benefit from nois ...

Successive approximation register analog-to-digital converters (SAR ADCs) have been widely used for medium-speed, medium-resolution applications due to their excellent power efficiency and digital compatibility. Recently ...

This thesis describes design techniques for high-performance switched-capacitor (SC) circuits, primarily for high-linearity low-noise SC circuits in the presence of component imperfections, such as nonlinear op-amp vol ...

A duty-cycle controlled switched resistor is a tunable resistive element that uses pulse width modulation as the method of tuning. This thesis will describe the operation of switched resistors and propose several circuit ...

The design of high-performance, high-speed clock generation and distribution becomes challenging in terms of phase noise, jitter and power consumption, due to the fast development of communication and computing systems. ...
