摘要：
A novel strategy of zero optimization in cascaded Sigma Delta modulators is presented. In the proposed structure, by using just an analog inter-stage feedback path, one pair of the noise transfer function (NTF) zeros is distributed over the desired bandwidth so that the in-band quantization noise is reduced. The effectiveness of the proposed modulator is verified by analytical calculations and simulation results.
