Abstract: Oversampling techniques based on sigma-delta (/spl Sigma//spl Delta/) modulation offer numerous advantages for the realization of high-resolution analog-to-digital (A/D) converters in low-voltage environment. This paper examines the design and implementation of a CMOS /spl Sigma//spl Delta/ modulator for digital-audio A/D conversion that operates from a single 1.8-V …
