Abstract :
A high-speed CMOS comparator for A/D convertors is discussed. The circuit has high resolution (better than 5 mV) in combination with high speed (clock frequencies up to 50 MHz). The advantage of the proposed structure is that no clock feedthrough is injected to the input, only one switch in a symmetrical structure is used and the effect of any current biasing on the comparator speed has been reduced
