Optical actuation and detection of MEMS resonators can improve the resolution of their motion detection compared to standard detection techniques (capacitive, piezoelectric). In this paper, a behavioral model of MEMS resonator with optical actuation and detection and the associated oscillator circuit are presented and used to determine its performances.
