Variable controller and associated control methods

Abstract

A circuit comprising a first capacitor configured to be charged to a voltage representing state information of a compensator, a second capacitor, a buffer circuit configured to charge the second capacitor to a voltage substantially equal to that of the first capacitor and a switching network configured to transition between a first state and a second state. When the switching network is in the first state, the second capacitor is charged to the voltage across the first capacitor. When the switching network is in the second state, the buffer circuit is disconnected from the second capacitor and the first capacitor and the second capacitor are connected in parallel.
