Abstract
Some embodiments provide a plurality of capacitors coupled in parallel, a plurality of capacitor switches, each one of the capacitor switches coupled in series with a respective one of the plurality of capacitors, one or more biasing circuits to independently set each of the plurality of capacitor switches to one of a reset voltage, a first threshold voltage, and a second threshold voltage, and a plurality of control switches, each of the control switches to couple and to decouple a respective one of the plurality of capacitor switches to and from a control voltage.
