Abstract :
This paper discusses the issues related to testing MEMS resonators, and suggests ways to mitigate the associated difficulties. Vacuum test conditions and their effect on the quality factor of a resonator are discussed. A custom-built vacuum system is described to simplify testing, and to avoid packaging at early stages of device characterization. Issues regarding the biasing and power handling of MEMS resonators are investigated, with specific attention given to electrostatic spring softening, and its effect on the response of the resonator. The use of MEMS resonators within an electronic oscillator is also discussed with respect to resonator non-linearity and phase noise performance.
