摘要

介绍了一种用于音频应用的数字A/D转换器。整个变换器仅由数字CMOS逻辑和一些电阻和电容组成。不需要线性放大器。这种A/D转换器大多采用纯数字设计。设计了一个动态范围为80db、输出采样率为44.1 kHz的20khz音频应用样机，并在0.18 /spl mu/m CMOS中进行了处理。

A 1.8 V digital A/D converter in 0.18 /spl mu/m CMOS

A digital A/D converter (DAD) for audio applications is presented. The whole converter consists only of digital CMOS logic and some resistors and capacitors. No linear amplifier is needed. This kind of A/D converter is mostly a pure digital design. A prototype for 20 kHz audio applications with a 80 dB dynamic range and 44.1 kHz output sample rate was designed and processed in 0.18 /spl mu/m CMOS.
