hi folks,
recently I'm designing a circuit which need a very accurate comparator.
the resolution must be smaller than 1mv.
also the offset has to be less than 2-3mv(3 sigma).
the process is tsmc13 logic. the area of it should be within 30umx30um
speed is not very critical, 30ns for settling is ok.
is that possible? how about if the offset can be 5mv(3 sigma)?
what should i concern more about? input pair size? layout?
is there anybody who has taped it out with the similar spec?
how about the really testing result?
thanks a lot
