ABSTRACT:
A clamp circuit includes a coupling capacitor connected between signal input and signal output terminals. A constant current sink and a controlled current source are connected to the output terminal. A comparator, coupled to the output terminal via a lowpass filter, generates signals for conditioning the controlled current source to source current whenever the output terminal exhibits a potential which differs from a predetermined reference in a predetermined polarity sense.
