Abstract
Some embodiments provide a plurality of capacitors coupled in parallel and a plurality of capacitor switches, each one of the capacitor switches coupled in series with a respective one of the plurality of capacitors. Also provided may be a plurality of control circuits, each of the plurality of control circuits coupled to a respective one of the plurality of capacitor switches, to generate a respective control voltage, and to independently set a respective one of the plurality of capacitor switches to the respective control voltage, and a plurality of control switches, each of the plurality of control switches to couple and to decouple a respective one of the plurality of control circuits to and from a control signal.
