首先引用一下《Delta-Sigma Data Converters . Theory, Design, and Simulation》在序言部分中的两小段话，作为今天的开场白。 “After all, the field of delta-sigma modulation encompasses many diverse disciplines: systems and control ...

The transition from second-generation (2G) to third-generation (3G) wireless cellular systems requires multi-standard adaptability in a wireless receiver. An important answer to this request is the ...

My last column showed how a single-stage delta-sigma modulator (DSM) produces an output that is a sum of the low pass-filtered input signal and the high pass-filtered quantization noise (see “Part 4,” ...

In this paper, we will attempt to explain sigma delta converters with a non-mathematical approach, covering the basic concepts of noise shaping and oversampling, explained with the help of some ...
