摘要: A sigma-delta modulator and an output rate reduction method are disclosed. The comprises integrator, analog-to-digital converter, a controller. An input signal is received by the integrator to generate integrated signal. then converted converter into digital modulation controller calculate power. can be controlled based on predetermined power value sum of total quantization error By way mentioned above, out reduced.
