摘要：

Adapting the loop filter in a sigma-delta modulator (SDM) increases the signal/noise ratio (SNR) at low input amplitudes, and also allows stable operation at high amplitudes where a fixed system would normally be unstable. Adaption is easily implemented in SDM digital/analogue converters (DACs).
