Mems oscillator thesis

Abstract this thesis provides analysis and modeling for one of the micro-eletro-mechanical system (mems) electrostatic actuator that consists of a micro-plate at the end of a cantilever. This thesis covers non-linearity effects of mems resonator in which a verilog-a mode of clamped-clamped (c-c) bearn resonator is presented so that electrical and mechani­ cal non-linearities are exposed with this madel. Mems oscillator suppliers solve the diversity problem by leveraging circuit technology while quartz oscillators are usually built with the quartz crystals driven at the desired output frequencies [ citation needed ] , mems oscillators commonly drive the resonators at one frequency and multiply this to the designed output frequency.
