compatro cmos circiut for high frequency

[nishagajare]

hello,
i want to design circuit of analog comparator for high frquency ,plz help me about cmos design of this comparator for high frquency......:sad:

You will probably trade accuracy for speed, and you can
expect some trouble measuring accuracy at speed on the
bench or ATE.

A plurality of high bandwidth low gain stages will work
better than a single or few high gain high impedance
stages. Though this can be prone to internal crosstalk
and oscillation at low input difference.

You are in a race between gm*Ro (gain) and Ro*Co
(bandwith) at every stage.
