1. A method, comprising:
driving a resonator mass of a gyroscope in a first direction by applying a first drive signal to a drive electrode;
applying a test voltage to a quadrature compensation electrode adjacent to the resonator mass;
reversing a polarity of the test voltage during application of the test voltage;
determining a phase difference between a first drive reference signal and an output signal of the gyroscope based on a change in the output signal during application of the test voltage; and
compensating for the phase difference between the first drive reference signal and the output signal of the gyroscope.
