20120062339 | MEMS NOTCH FILTER AND METHOD - A MEMS notch filter comprises a frame; a movable mass; resilient members connecting the mass to the frame; electrodes connected to the frame; and a comb drive connected to the frame and the mass which operates to drive the mass, wherein the filter is adapted to oscillate at least one resonant frequency. A mechanism is positioned below the mass, wherein the mechanism is adapted to maintain a neutral position of the mass and to expel fluid onto the mass. The comb drive is adapted to receive an applied voltage signal from the electrodes. This voltage signal is applied to the comb drive at a resonant frequency of the notch filter and induces the mass to oscillate in a geometric plane of the frame (or optionally in some other resonant mode); resulting in dissipation of energy and voltage attenuation. Other voltage components not at the notch frequency are not attenuated. | 03-15-2012 |
