Abstract
An embodiment of a tunable capacitor can include a plurality of capacitors connected in series where at least two capacitors of the plurality of capacitors share a common electrode where the at least two capacitors are in lateral proximity and a bias that is capable of being applied to the at least two capacitors whereby the at least two capacitors vibrate in opposite phase to each other when the bias and an RF signal is applied to the at least two capacitors.
