Abstract
Systems and methods for an encoder and control scheme are provided. In one embodiment, a micro-electromechanical system (MEMS) device comprises: a stator having a first marker and a second marker arranged on a surface of the stator to form a sensing pattern; a sweeping element that dithers in a plane parallel to the surface of the stator along a sweep path that crosses the first marker and a second marker; an overlap sense circuit operable to measure an area overlap between the sweeping element and the sensing pattern, wherein the overlap sense circuit generates a pulse train signal output that varies as a function of the area overlap.
