Abstract :
The conditions for a lowpass sigma-delta modulator stably operated in optimization mode are derived. In this mode of operation, the stability and performance of the modulator can be rigorously analyzed. Based on the analysis, an effective design method is presented for designing a lowpass modulator of arbitrary order.
