C-Simulator for Over-sampling ΣΔ A/D Converters

摘要

This paper will present a C-simulator for over-sampling ΣΔ A/D converters. This simulator consists of a ΣΔ 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 ΣΔ A/D converters.
