Abstract

In this paper, we report a 6.3MHz Lamé-mode square resonator with fully differential drive and sense electronics, exhibiting quality factor, Q values exceeding 1 million in ambient pressures as high as 100Pa. A maximum Q value of 1.6 million was experimentally measured at vacuum pressure of 36 μTorr. It was also experimentally observed that the Q value for the bulk mode resonator was relatively independent for pressures below 100Pa suggesting that the Q is pressure limited for pressure higher than 100Pa. This resonator was fabricated using SOIMUMPs process from MEMSCAP.
