ABSTRACT:
A DC clamping circuit acting on an input signal to clamp the input signal to a voltage reference is disclosed. The DC clamping circuit comprises a comparator providing an output that decreases whenever the input signal is less than the output. A capacitor is connected to the output of the comparator for absorbing the charge output by the comparator. Finally, a differential amplifier is provided for subtracting the output of the comparator from the input signal and for adding the voltage reference.
