Abstract: A control system includes sensor controllers that are each coupled to a respective set of electrodes of a CVG sensor system via respective sensor channels. A first portion of the sensor controllers provides a sinusoidal forcer signal on the respective sensor channel in response to digital clock and feedback signals to provide oscillation of a resonator of the CVG sensor system. A second portion of the sensor controllers monitors a capacitive pickoff voltage associated with the resonator on the respective sensor channel to generate a digital pickoff signal. A gyroscope controller generates the digital feedback signal in response to the digital pickoff signal from the second portion of the sensor controllers to provide the digital feedback signal and the digital clock signal to the first portion of the sensor controllers and determines a rotation about the CVG sensor system based on the digital feedback signal or the digital pickoff signal.

Abstract: A system includes a capacitance sensor having an inertial proof mass disposed between a first electrode structure and a second electrode structure. A switching system is switchable between providing one of a positive charge pulse and a negative charge pulse to one of the first electrode structure and the second electrode structure. A controller controls the switching of the switching circuit to provide one of the positive charge pulse or the negative charge pulse to the first electrode structure during a first portion of a charge cycle time period and to provide an opposite polarity charge pulse from that provided to the first electrode structure to the second electrode structure during a second portion of the charge cycle time period to generate an error signal with respect to the inertial proof mass of the capacitance sensor.
