摘要: A resonator has a main resonator body and a secondary resonator structure. The resonator body has a desired mode of vibration of the resonator alone, and a parasitic mode of vibration, wherein the parasitic mode comprises vibration of the resonator body and the secondary resonator structure as a composite body. In this way, unwanted vibrational modes are quenched by the second suspended body.

摘要: A resonator in which in addition to the normal anchor at a nodal point, a second anchor arrangement is provided and an associated connecting arm between the resonator body and the second anchor arrangement. The connecting arm connects to the resonator body at a non-nodal point so that it is not connected to a normal position where fixed connections are made. The connecting arm is used to suppress transverse modes of vibration.

摘要: A MEMS resonator system that reduces interference signals arising from undesired capacitive coupling between different system elements. The system, in one embodiment, includes a MEMS resonator, electrodes, and at least one resonator electrode shield. In certain embodiments, the resonator electrode shield ensures that the resonator electrodes interact with either one or more shunting nodes or the active elements of the MEMS resonator by preventing or reducing, among other things, capacitive coupling between the resonator electrodes and the support and auxiliary elements of the MEMS resonator structure. By reducing the deleterious effects of interfering signals using one or more resonator electrode shields, a simpler, lower interference, and more efficient system relative to prior art approaches is presented.

摘要: A microelectromechanical system (MEMS) resonator includes a resonant semiconductor structure, drive electrode, sense electrode and electrically conductive shielding structure. The first drive electrode generates a time-varying electrostatic force that causes the resonant semiconductor structure to resonate mechanically, and the first sense electrode generates a timing signal in response to the mechanical resonance of the resonant semiconductor structure. The electrically conductive shielding structure is disposed between the first drive electrode and the first sense electrode to shield the first sense electrode from electric field lines emanating from the first drive electrode.
