ΣΔ调制器的设计方法

Methodology of Sigma Delta Modulator Design

介绍了sigma delta单环调制器的设计方法。详细阐述了如何把给定的要求转化为具体拓朴结构。通过该方法,设计者可以在仅知道精度要求的情况下,逐步实现所需要的电路结构,并通过一个三阶一位调制器的设计描述了这一流程。

This paper introduces a methodology of sigma delta modulator design. For given performance, this methodology will guide the designer to select specified configuration to fit the requirements. And an example of design a modulator with SNR equals 100 dB, we demonstrate the process from step to step.
