Abstract :
A high performance auto-zeroing and auto-resetting CMOS comparator is presented which possesses a fast recovery time from saturation. Experimental results indicate such a comparator resolves 20 mu V in less than 0.5 mu s, thus making it suitable for high resolution analogue-to-digital convertors with conversion speed up to 100 kilosamples per second.
