Abstract:
1. A resonator comprising: a translator including a first set of translator electrodes commonly connected to a first translator voltage and a second set of translator electrodes commonly connected to a second translator voltage, wherein the first set of translator electrodes are arranged on the translator alternatively with the second set of translator electrodes; a stator including a first set of stator electrodes commonly connected to a first stator voltage, a second set of stator electrodes commonly connected to a second stator voltage, and a third set of stator electrodes commonly connected to a third stator voltage, wherein the first set of stator electrodes are arranged on the stator alternatively with the second and third sets of stator electrodes; and a control circuit configured to provide the first and second translator voltages and first through third stator voltages, wherein the translator is configured to move with respect to the stator at a resonant frequency of the resonator in response to the control circuit.
