Design of Low Power and Low Area Passive Sigma Delta Modulators for Audio Applications
Springer International Publishing (Verlag)
978-3-319-57032-7 (ISBN)
This book presents the study, design, modulation, optimization and implementation of low power, passive DT-SigmaDeltaMs for use in audio applications. The high gain and bandwidth amplifier normally used for integration in SigmaDelta modulation, is replaced by passive, switched-capacitor branches working under the Ultra Incomplete Settling (UIS) condition, leading to a reduction of the consumed power. The authors describe a design process that uses high level models and an optimization process based in genetic algorithms to achieve the desired performance.
