Abstract
A gyroscope system may include a disc resonator gyroscope including a plurality of electrodes embedded in the disc resonator gyroscope. The electrodes may be configured for at least applying a drive voltage and a tuning voltage to the disc resonator gyroscope and for sensing operating parameters of the disc resonator gyroscope. The gyroscope system may also include a quadrature stabilization circuit configured to measure a quadrature error and generate a quadrature regulating voltage based on the quadrature error. The tuning voltage may be adjusted by the quadrature regulating voltage to cancel an effect of voltage flicker before being applied to a tuning electrode of the disc resonator gyroscope.
