Advanced data converter design techniques

Abstract

As IC process technologies have progressed, noise-shaping data converters, already known for their superior linearity performance, have steadily overtaken wider bandwidth applications previously dominated by Nyquist-rate data converters. This talk will start with the fundamental concepts of noise-shaping converters and also cover some of the more recent architectural innovations that have led to the dominance of the sigma-delta data converter as the choice for a wide variety of high resolution-bandwidth applications including wireless receivers. A brief case study of a multi-bit sigma-delta ADC design for a receiver application will help to illuminate some of the key considerations involved in noise-shaping data converter circuit design.
