Abstract
One embodiment disclosed relates to a method for driving a micro electromechanical (MEM) device. The method includes generating a high-frequency AC drive signal that is substantially greater in frequency than a resonance frequency of a movable feature in the MEM device, and modulating the amplitude of the high-frequency AC drive signal. A DC-like displacement of the movable feature in the MEM device is achieved by driving the movable feature using the amplitude modulated high-frequency AC drive signal.
