Abstract
A current leakage mitigation circuit is provided. The circuit includes a charge storage circuit for receiving a control signal output, and a correction circuit connected to a bottom plate of the charge storage device. The control signal is output by an amplifier circuit connected to the current leakage mitigation circuit. The correction circuit samples the control signal, applies a filter to the control signal for to extracting a predefined frequency component, amplifies the filtered control signal, and applies the amplified control signal to the bottom plate of the current storage device.
