Title: the role of peaking capacitor
Post by lhlbluesky_lhl on Mar 5^th, 2013, 5:44am

what is the role of a peaking capacitor in the circuit? just as the picture shows, Cp is a peaking capacitor, how can it influence the peaking behavior? in some paper, Cp = 3% of C1, is that right? how to choose the proper value of Cp? assuming that, in the following picture, C1=1nF, R1=10k.
thanks.

hello,
whats your application, are you going to equalize some data or what?

But here peaking capacitor is not doing any thing except reducing high frequency gain.

Thanks,
Raj.
