ABSTRACT:
A charge control circuit for controlling a micro-electromechanical device having a variable capacitance is disclosed. In one embodiment, a charge storage device is configured to store a charge amount. A switch circuit is configured to control the variable capacitance of the micro-electromechanical device by sharing the charge amount between the charge storage device and the micro-electromechanical device to equalize the charge storage device and the micro-electromechanical device to a same voltage.
