摘要

A-t -一种任意阶σ - δ调制器级联结构，由于缩放问题，即使使用单比特量子化，也只有1比特的分辨率损失。无论顺序如何，这种损失都保持在一个高过载点。仿真结果表明，电路缺陷可以容忍到6阶，因此x16过采样可以获得90 db的SNDR，而不需要多比特量化。

Expandible high-order cascade ya modulator with constant, reduced systematic loss of resolution

A-t - An arbitrary order sigma-delta modulator cascude architecture is presented with only I-bit loss of resolution due to scaling issues, even with single-bit quantizulion. This loss is kept with a high overloading point, regardless of the order. Simulations reveol that circuit imperfections can be tolerated up to 6th order, so that 90-dB SNDR can be obtained with x16 oversampling, without multi-bit quantization.
