Abstract
A method of calibrating a resonator having a resonant member that can vibrate in a first mode of vibration, and a calibration electrode that is spaced from a capacitively coupled to the resonant member, the method comprises: applying a polarization voltage to the resonant member and a calibration voltage to the calibration electrode, wherein the polarization voltage is a negative voltage; vibrating the resonant member such that the resonant member vibrates in the first mode of vibration; measuring a frequency parameter of the resonant member; determining if the frequency parameter is in compliance with a predetermined threshold; and if the frequency parameter is not in compliance with the predetermined threshold, adjusting the frequency parameter to be in compliance with the predetermined threshold by adjusting at least one of the polarization voltage and the calibration voltage.
