ABSTRACT:
The gyro sensor uses a clock signal as a timing signal or synchronous signal for reading various data stored in a built-in memory for its yaw rate sensing operation. The gyro sensor is configured to use, as such a clock signal, the self-excited oscillation signal being applied to the vibrator of the gyro sensor as a vibrator drive signal.
