Abstract
An apparatus, system and method for clamping a video signal input to a coupling capacitor () for providing a clamping voltage. A charging current is applied to the capacitor () via an amplifier () having a first input () coupled with the capacitor output and a second input () coupled to a reference potential, the amplifier () is responsive to the capacitor output signal and the reference potential for providing the charging current to the capacitor (). The current has a linearly varying magnitude which is proportional to a difference between the capacitor output and the reference potential.
