Abstract: Parameters, such as, quality factor and/or resonance frequency of an acoustic transducer can be electrically tuned. The acoustic transducer can include a piezoelectric layer deposited on a silicon supporting layer, a first electrode layer deposited on the piezoelectric layer, and a second electrode layer deposited between the silicon supporting layer and piezoelectric layer. In one aspect, a resonant frequency of the piezoelectric actuated transducer is electrically tuned based on modifying a voltage across at least a portion of the first electrode layer and the second electrode layer. In another aspect, a quality factor of the piezoelectric actuated transducer is electrically tuned based on modifying a resistance across at least another portion of the first electrode layer and the second electrode layer.

Abstract: A system and/or method for efficiently operating a MEMS gyroscope without drive circuitry and/or with drive circuitry and a non-constant oscillating amplitude. In a non-limiting example, drive circuitry may be utilized to drive the MEMS gyroscope proof mass to a desired oscillating amplitude, and then the drive circuitry may be powered off. Rotational velocity may be sensed while the proof mass is being driven to a desired oscillating amplitude, while the proof mass is being maintained at a desired oscillating amplitude, and/or while the proof mass amplitude decays.
