I want a simple cmos comparator with cmos gates.
spec: single supply, VCC=2.5-3.3v
propagation delay under 10ns.
fewer gates as possible.

Any idea?


thanks
Andrew

The only solution is a latch based comparator with pre-amp input stage. Most of time, you can get <10ns delay

how about your input amplitude? if it is large, only latch is okay for you

Check Allen's or Martin's Cmos design book. There is chapter about comparator

What's the resolution of your comparator?
