  "textContent": "An auto phase control drive circuit for a gyroscope apparatus is disclosed. The gyroscope apparatus has a gyro resonator, and the circuit comprises a first circuit and a second circuit. The first circuit includes a first electrode configured to face the gyro resonator, a first amplifier configured to be electrically connected with the first electrode and output a first signal, a variable capacitor electrically connected with the first amplifier, a second electrode configured to face the gyro resonator, to receive a second signal and to be electrically connected with the variable capacitor. The second circuit is configured to be electrically connected with the first circuit and to change a capacitance of the variable capacitor of the first circuit based on the first signal and the second signal to decrease a phase difference between the first signal and the second signal.",
