Delta-Sigma Data Converters: Theory, Design, and Simulation
This comprehensive guide offers a detailed treatment of the analysis, design, simulation and testing of the full range of today's leading delta-sigma data converters. Written by professionals experienced in all practical aspects of delta-sigma modulator design, Delta-Sigma Data Converters provides comprehensive coverage of low and high-order single-bit, bandpass, continuous-time, multi-stage modulators as well as advanced topics, including idle-channel tones, stability, decimation and interpolation filter design, and simulation.
Why Read This Book
You should read this book if you need a rigorous, practical foundation in delta-sigma modulator theory and end-to-end converter design. It teaches both the analytical tools and simulation practices you’ll use to design, analyze, and verify modern sigma-delta ADCs/DACs, including decimation/interpolation filter design and stability/idle-tone issues.
Who Will Benefit
Practicing DSP and mixed-signal engineers or graduate students who design or validate ADC/DAC front ends for audio, communications, and instrumentation systems.
Level: Advanced — Prerequisites: Undergraduate-level knowledge of signals and systems (sampling, linear systems, z-transform), basic probability/quantization theory, and familiarity with digital filter design and circuit simulation concepts.

How It Compares
Covers similar foundational ground to Schreier & Temes' later 'Understanding Delta-Sigma Data Converters' (which is more up-to-date), and complements general ADC design texts by focusing deeply on modulator theory and decimation filter integration.
