Q-Compensation Circuit for a Planar Vibratory Microgyroscope

Electronic circuitry has been devised to compensate for variations in the resonance quality factor (Q) of a planar vibratory microgyroscope like that described in the first of the two preceding articles. That is, the circuit makes the scale factor of the gyroscope (the factor of proportionality between the rate of rotation, W, and the output signal) independent of Q.
