Abstract
A CVG having first and second degenerate resonator modes with each a damping rate; drive circuits for causing the resonator to oscillate in the first and second modes in response to first and second drive signals; first and second sense circuits for generating first and second sense signals in response to the resonator oscillating in the first and second modes; a signal processing circuit having control loops for generating the first and second drive signals based on the first and second sense signals; and first and second damping feedback circuits for generating first and second damping feedback signals proportional to the first and second damping rates; an adding the damping feedback signals to the first and second drive signals.
