Abstract
A CVG having an axisymmetric resonator with first and second degenerate vibratory modes, having respectively first and second mode resonance frequencies (ω1, ω2) wherein said first and second mode resonance frequencies differ by a frequency difference (Δω); a plurality of electrodes arranged at a distance around a periphery of the resonator; said plurality of electrodes comprising at least one resonance frequency tuning electrode arranged for, upon application of a first bias voltage signal to said at least one resonance frequency tuning electrode, acting on the frequency difference (Δω) by changing at least one of the first and second mode resonance frequencies; and a resonance frequency loop circuit arranged to generate said first bias voltage signal and regulate a value of said first bias voltage signal to maintain said frequency difference (Δω) at a predetermined minimal value.
