摘要

介绍了一种70 MS/s的CMOS A/D转换器。采用时间交错结构，采用4条双采样差分开关电流管道，实现高采样率。解决的具体问题是信号副本的匹配，同时保持全模拟带宽，并尽量减少传播过程中的信号损坏。实验变换器采用标准的0.8 /spl mu/m 5 V数字CMOS工艺制作，无需特殊选择。

A 70 MS/s 8-bit differential switched-current CMOS A/D converter using parallel interleaved pipelines

A 70 MS/s CMOS A/D converter is presented. Four double-sampling differential switched-current pipelines are used in a time interleaved structure to achieve a high sampling rate. Particular issues addressed are the matching of signal copies whilst maintaining full analogue bandwidth, and minimising signal corruption during propagation. The experimental converter is fabricated in a standard 0.8 /spl mu/m 5 V digital CMOS process without special options.
