摘要：
A vibration gyro sensor is provided which is capable of generating time information and detecting an angular velocity. A driving signal for driving a tuning fork piezoelectric vibrating reed is generated based on an excitation signal generated by an oscillation circuit. An angular velocity signal is obtained based on a detection signal generated by a detection electrode of the tuning fork piezoelectric vibration reed. The excitation signal generated by the oscillation circuit is input to a divider such that a timer clock signal is generated.
