ABSTRACT:
A highpass feedback loop for A.C. coupled amplifier circuits is disclosed, by means of which pulse undershoot recovery is accelerated. The feedback loop includes an operational amplifier which goes into limiting above a selected amplitude threshold so that for pulses exceeding the threshold the amplifier frequency response is unaffected.
