hello,
can any one suggest a peak detector for my AGC?

I have trans impedance with 150 gain followed by a AGC whose gain changes from 2 to 5 because my receiver gain has to be programmable from 300 to 750, but for me peak detector is giving is problem (basically it's a differential pair with some capacitor at the tail node)

Thanks,
Raj.

Hello,
Thanks for the reply, at present i am using square based Peak detector(basically a gilbert multiplier with input shorted). My question is how to find the incremental model for this to estimate the loop dynamics, i am not finding any clear document for the AGC loops, i guess even other kind of detectors (rectifier,RMS) model is same as my detector.

I will be happy if some helped me this problem.

Thanks,
Raj
