Abstract
An angular sensor. The angular sensor includes a Coriolis vibratory gyroscope (CVG) resonator, configured to oscillate in a first pair of normal modes including a first normal mode and a second normal mode and a second pair of normal modes including a third normal mode and a fourth normal mode. The angular sensor further includes a coarse readout circuit configured to drive the first pair of modes, measure the motion of the first pair of modes, and derive from the measured motion of the first pair of modes a coarse measurement of an angular rate of the resonator. The angular sensor further includes and a fine readout circuit configured to derive a measurement of the difference between the true angular rate of the resonator and the coarse measurement.
