摘要：

It has been shown that a multibit SigmaDelta modulator can be built replacing the multibit quantizer in the forward path by a single-bit one, operating at a higher frequency, by an increase in the oversampling ratio of the last integrators of the loop. An improved topology is proposed here which obtains similar performances with single-bit feedback, overcoming drawbacks inherent to high resolution digital to analog converters.
