摘要：
Sigma-delta ADC outperforms the Nyquist ADC in precision and robustness by using oversampling and noise shaping. A fourth-order sigma-delta modulator of input feedforward architecture is designed and simulated in system-level. Input feedforward architecture has advantages of low output swing of integrators and simple structure. Proper circuit parameters are also presented in this paper. The simulation revealed that the modulator achieves 109 dB dynamic range in a signal bandwidth of 1 KHz with a sampling frequency of 250 KHz.
