An overview on computer-aided analysis techniques for sigma-delta modulators

An overview is presented on the state-of-the-art in the field of computer-aided circuit analysis of sigma-delta modulators, with special attention paid to the analysis of nonideal effects like circuit noise and clock jitter. A new simulator-SDNoise, which can be used for noise, clock jitter and dithering analysis of sigma-delta modulators at electrical circuit level, is introduced.
