ABSTRACT:
A capacitance-sensing vibratory gyro includes a capacitance-sensing circuit that detects changes in capacitances of a sensing element. The capacitance-sensing circuit includes two operational amplifiers. The inverting input terminal of each operational amplifier is connected to the corresponding sensing electrode in the sensing element. A bias voltage generated by dividing a power supply voltage with resistors is applied to the non-inverting input terminals of the operational amplifiers. The bias voltage is applied to each sensing electrode by imaginary short-circuiting in the operational amplifiers so that the bias voltage directly depends on the power supply voltage.
