Abstract
A MOS-type semiconductor input capacitor protection circuit and system is described. In one embodiment, the system includes a MOS device configured as an input capacitor and configured to receive an input bias voltage. A bias monitor circuit is configured to monitor the input bias voltage and apply a selective capacitor bias voltage to the input capacitor so as to limit the voltage across the input capacitor to a level below a threshold voltage.
