I have a question regarding inductive peaking circuits.
Many variations of inductive peaking such has series, shunt and combination of the two have been used widely to increase the bandwith of amplifiers, but what is the price we pay in return....ofcourse chip area is one but what about delay of the signal from input to output ?
Lets say that a combination of series and shunt peaking is used in a differential amplifier, and 4 stages of such amplifiers are cascaded to form a ring oscillator...Will the oscillation frequency of the ring oscillator increase or decrease?
In my opinion the Oscillation frequency should decrease as the delay is being increased by inductors, however the BW is increased? Can anybody confirm/elaborate on this?
Regards
