This paper designs a three cascaded sigma-delta modulator with using mash structure. Analysis of gain coefficient of each module and simulate the modulator for the behavioral level. In 0.5μm CMOS process conditions, the input signal bandwidth is 20 kHz, oversampling rate is 256, SNR of the simulation model can get 100.5 dB, and accuracy is greater than 16 bit. Compared with other structures of the modulator, it has more stable and more dynamic range, so it can be applied to audio-frequency circuit.
