摘要
提出了一种无需外部时钟、可以部分抵消工艺偏差、基于标准单元的延迟环A/D变换器.该A/D变换器结构简单、无需增加产生控制信号的电路,转换速度快,可在DC/DC变换器的高频数字控制芯片中使用.
A non-clock delay-ring A/D converter is presented,which is based on standard cell library and not sensitive to process variation.The architecture of this A/D converter is simple,and its speed is high. Meanwhile there is no need of any control signal.This A/D converter can be used in high-frequency digital control chip of DC/DC converter.
