Tones, saturation, and SNR in double loop /spl Sigma//spl Delta/ modulators
Two of the most important factors affecting the performance of oversampled A/D converters are tone, and saturation considerations. Tradeoffs between the above factors for /spl Sigma/-/spl Delta/ modulators are analyzed. The effects of pole placement on the steady state behavior of /spl Sigma/-/spl Delta/ modulators are investigated by studying the dynamics of an associated continuous time system.<<ETX>>
