Hello jerryzhao,
Thanks for your reply.
Actually, the closed-loop gain doesnt have to be programmable; closed-loop gain of for example 0dB is ok.
If the track and hold circuit has a closed-loop gain of 0dB, then it is enough I think; maybe it is not exactly 0dB.
However, is the realization of the amplifier part of the Track and Hold circuit just a diff. pair with differential input and differential output?
If I, for exmple, build a cmos opamp with a large open-loop gain, will this be the opamp symbol in the Track and Hold circuit?
One more thing: What do you mean by no-overlap clock circuit?
greetz,
