ABSTRACT:
A gyroscope system can detect the amount of movement of the system. The gyroscope system includes a circuit that has a number of different features and detects movement independent of any circuit parameters. The first feature uses a feedback loop to compensate for difference in Q factors between the circuits. Another feature regulates the amplitude of the resonator. Yet another feature extracts the rotation rate signals from the gyroscope in a new way.
