Abstract

Vibratory gyroscopes exploit a coriolis force coupling between two degrees of freedom internal to the sensor for detection of the sensor´s angular rotation rate. Vibratory gyroscopes provide ubiquitous opportunities for local feedback compensation to achieve harmonic excitation of selected modes, disturbance rejection, and tuning of the sensor´s dynamics. This paper describes the design and preliminary testing of an application specific integrated circuit (ASIC) that performs some of these control tasks in addition to the signal demodulation required for the detection of the rate-induced response
