Abstract
A PM signal generator can generate a variable PM signal based on a position of a movable element of a MEMS motor. A bias voltage generator can provide a bias voltage to the MEMS motor. The bias voltage generator can include a reference signal generator that can generate a reference signal that varies based on variation of pulses of the PM signal. The bias voltage can be based on the reference signal.
