چکیده

The following work reports the design, numerical, analytical and simulation characterization of an Aluminum Nitride MEMS resonator. The paper offers a comparison of rectangular plate MEMS resonator (length extensional and width extensional mode shapes) and ring shape MEMS resonator. It also demonstrates the contour Eigen modes of resonators and their equivalent electric circuit model (BVD). Furthermore, an overview of a band pass filter that can be enabled by mechanical coupling of these counter mode resonators is briefly presented. Keywords— MEMS resonator, Contour mode, Electromechanical coupling, Aluminum Nitride, Tethers.

Fabrication and Modeling of Piezoelectric RF MEMS Resonators

Resonators serve as essential components in radio-frequency (RF) electronics, forming the backbone of filters and tuned amplifiers. However, traditional solid state or mechanic implementations of resonators and filters tend to be bulky and power hungry, limiting the versatility of communications, guidance, and avionics systems. Microelectro-mechanical systems (MEMS) are promising replacements f...
