Abstract
A circuit for clamping a TV signal includes an input capacitor coupled to the TV signal, an analog-to-digital converter that outputs a digital signal corresponding to TV signal, a comparator that compares the digital signal to a black level signal, and a high impedance driver that charges the input capacitor in response to an output of the comparator.
