C-simulator for over-sampling ΣΔ A/D converters

This paper will present a C-simulator for over-sampling /spl Sigma//spl Delta/ A/D converters. This simulator consists of a /spl Sigma//spl Delta/ modulator, a comb filter with decimation and lowpass wave digital filters. The simulator can verify the architecture of the above mentioned three parts and evaluate the precision of /spl Sigma//spl Delta/ A/D converters.
