High Speed and Wide Bandwidth Delta-Sigma ADCs [Paperback]

This book describes techniques for realizing wide bandwidth (125MHz) over-sampled analog-to-digital converters (ADCs) in nano meter-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?) 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 ??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 ??Ms, aiming at a GHz sampling frequency.Introduction.- Continuous-Time Delta-Sigma Modulator.- Continuous-Time Delta-Sigma Modulators at High Sampling Rates.- A 4GHz Continuous-Time ??
