The present invention is a gyro sensor driver circuit, to a gyro sensor system, a gyro sensor and a driving method. According to one embodiment of the present invention, receives a converted signal from an output signal of the gyro sensor drive signal generator for generating a drive signal to be applied to the gyro sensor; Resonance determination unit receives the demodulated signal or a drive signal for demodulating the output signal or receive the output signal of the gyro sensor for determining whether resonance of the gyro sensor; Determining the resonance and a resonance portion determined when the drive signal is to be applied when a gyro sensor, a start-up signal that may cause resonance of the resonance ratio determination portion determines the resonance when the gyro sensor unit such that the start signal is applied to the gyro sensor; Is a gyro sensor including a drive circuit is proposed. In addition, the gyro sensor and gyro sensor system drive method is proposed to include him. ; 展开▼
