基于MEMS方块谐振器的10 MHz振荡器
A 10 MHz oscillator using square MEMS resonator
摘要
Abstract
The quality factor of square Micro Electromechanical System(MEMS) resonator is very high, whereas the insertion loss is very big. In order to obtain MEMS oscillator with low phase noise, the quality factor of square resonator is further improved, and the insertion loss is lowered. By reasonable designing, the exact support beam locations can minimize the anchor loss,and the proposed resonator achieves very high quality factor. The design method of Second-Mode Face Shear Square Micromechanical Resonator bears many advantages: higher quality factor and lower dynamic resistance(reaches 82.1Ω at 0.25μm gap). The oscillator based on this newly designed resonator achieves a lower phase noise: -156 dBc/Hz @1 kHz.关键词
