    Abstract: A micro-gyroscope (10) having closed loop output operation by a control voltage (Vty), that is demodulated by a drive axis (x-axis) signal Vthx of the sense electrodes (S1, S2), providing Coriolis torque rebalance to prevent displacement of the micro-gyroscope (10) on the output axis (y-axis) Vthynull0. Closed loop drive axis torque, Vtx maintains a constant drive axis amplitude signal, Vthx. The present invention provides independent alignment and tuning of the micro-gyroscope by using separate electrodes and electrostatic bias voltages to adjust alignment and tuning. A quadrature amplitude signal, or cross-axis transfer function peak amplitude is used to detect misalignment that is corrected to zero by an electrostatic bias voltage adjustment. The cross-axis transfer function is either Vthy/Vty or Vtnx/Vtx. A quadrature signal noise level, or difference in natural frequencies estimated from measurements of the transfer functions is used to detect residual mistuning, that is corrected to zero by a second electrostatic bias voltage adjustment.

    Abstract: A gyroscope system can detect the amount of movement of the system. The gyroscope system includes a circuit that has a number of different features and detects movement independent of any circuit parameters. The first feature uses a feedback loop to compensate for difference in Q factors between the circuits. Another feature regulates the amplitude of the resonator. Yet another feature extracts the rotation rate signals from the gyroscope in a new way.

    Abstract: A semiconductor accelerometer includes a mass portion formed at a center of a silicon plate, a frame portion formed around the circumference of the silicon plate so as to surround the mass portion and a diaphragm portion formed in the silicon plate between the mass portion and the frame portion so as to bridge the mass portion with the frame portion, one of major surfaces of the silicon plate serving as a common continuous major surface for the mass portion, frame portion and diaphragm portion. Piezoresistance elements are formed on the common continuous major surface at the diaphraqm portion and an additional Au film is formed on the common continuous major surface at the mass portion. The additional Au film constitutes in combination with the mass portion a weight which responds to an acceleration acting thereon. The mass of the additional Au film is selected in such a manner that the center of gravity of the weight is located within an area in the mass portion having a depth corresponding to the thickness of the diaphragm portion.
