High speed and wide bandwidth delta-sigma ADCs

This book describes techniques for realizing wide bandwidth (125MHz) over-sampled analog-to-digital converters (ADCs) in nanometer-CMOS processes. The authors offer a clear and complete picture of system level challenges and practical design solutions in high-speed Delta-Sigma modulators. Readers will be enabled to implement ADCs as continuous-time delta-sigma (CT[delta][sigma]) modulators, offering simple resistive inputs, which do not require the use of power-hungry input buffers, as well as offering inherent anti-aliasing, which simplifies system integration. The authors focus on the design of high speed and wide-bandwidth [delta][sigma]Ms that make a step in bandwidth range which was previously only possible with Nyquist converters. More specifically, this book describes the stability, power efficiency, and linearity limits of [delta][sigma]Ms, aiming at a GHz sampling frequency. -Provides overview of trends in Wide Bandwidth and High Dynamic Range analog-to-digital converters (ADCs); -Enables the design of a wide bandwidth, high dynamic range modulator with state-of-the-art power efficiency; -Includes introduction to Continuous-Time Delta-Sigma Modulators and its system level modeling; -Explains issues relating to stability of Continuous-Time Delta-Sigma Modulators; -Includes discussion of system level non-idealities in Continuous-Time Delta-Sigma Modulators; -System level design of CT[delta][sigma] modulators at GHz sampling frequencies; -Practical implementation details of high speed CT[delta][sigma] ADCs; -Overview of static and dynamic error correction techniques in [delta][sigma] ADCs; -Dynamic error correction techniques that are suitable for high speed CT[delta][sigma] ADCs.
