In this paper, we report the first fully-differential, electrostatically transduced RF MEMS resonator. The fullydifferential electrode configuration not only cancels capacitive feedthrough between the drive and sense terminals but also eliminates the reduction in electromechanical quality factor (Q) from the large ohmic resistance of the polycrystalline silicon carbide (poly-SiC) suspension and anchor. Using this configuration, we have demonstrated a 173 MHz poly-SiC Lamé-mode resonator with adoi:10.1109/memsys.2005.1453907 fatcat:ai64krm54ndc7puexktvqtpnqu
