1. A method of compensating a gyroscope for bandwidth sensitivity, the method comprising:

  • generating a test signal;

    generating a quadrature error signal using a received Coriolis sense signal;

    detecting a phase difference between the quadrature error signal and the test signal;

    determining a bandwidth of the gyroscope based on the detected phase difference; and

    compensating the gyroscope for bandwidth sensitivity by using the Coriolis sense signal and the bandwidth of the gyroscope.
