摘要： A piezoresistive MEMS oscillator comprises a resonator body, first and second drive electrodes located adjacent the resonator body for providing an actuation signal; and at least a first sense electrode connected to a respective anchor point. The voltages at the electrodes are controlled and/or processed such that the feedthrough AC current from one drive electrode to the sense electrode is at least partially offset by the feedthrough AC current from the other drive electrode to the sense electrode.

摘要： A resonator comprises a resonator mass (34), a first connector (30) on a first side of the mass connected between the resonator mass and a first fixed mounting and a second connector (32) on a second, opposite, side of the mass connected between the resonator mass and a second fixed mounting. Drive means drives the mass (34) into a resonant mode in which it oscillates in a sideways direction, thereby compressing one of the first and second connectors while extending the other of the first and second connectors.

摘要： A MEMS resonator has a component which provides a capacitance associated with the transduction gap which has a temperature-dependent dielectric characteristic, which varies in the same direction (i.e. the slope has the same sign) as the Young's modulus of the material of the resonator versus temperature. This means that the resonant frequency is less dependent on temperature.

摘要： A device has a micro electromechanical structure (10) with a first arm (102), at least one second arm (104a, b) connected to each other via a connection (100). Both arms (102, 104a, b) and the connection (100) are preferably made of a single crystalline body. The first and second arm (102, 104a, b) have end portions attached to a substrate, but otherwise the arms and their connection are free to move relative to the substrate. The first and second arm (102, 104a, b) extending from the end portions to the connection (100) along different directions, preferably perpendicularly to each other. An electrode (12) is provided on the substrate, adjacent to the micro electromechanical structure (10) to excite vibration of the structure. The two arms in different directions make it possible to reduce the nonlinearity of the stiffness during vibrations of the structure.
