Abstract
A switchable capacitor including a first electrode, a dielectric layer on the first electrode, a second electrode configured to be suspended in an undeflected position over the dielectric layer in a de-activated state, and to deflect toward the first electrode in an activated state in response to a voltage difference between the two electrodes, a gap between the second electrode and the dielectric layer in the activated state being less than a corresponding gap in the de-activated state, and a capacitor having a first and second end, coupled to one of the electrodes at the first end, and configured to reduce the voltage difference between the electrodes as the second electrode deflects toward the first electrode in the activated state, wherein the voltage difference between the electrodes corresponds to a bias voltage applied across the second end of the capacitor and an other one of the first and second electrodes.
