Vibratory gyro sensor system

A vibratory gyro sensor system, comprising:

• a driving unit shifting a signal output from a first sensing element of a gyro sensor by a preset shift phase, amplifying the phase shifted signal to a preset gain, and self-oscillates the amplified signal to generate and feedback a driving signal;
• an automatic gain control unit receiving the amplified signal of the driving unit, detecting peak voltage and quantizing the detected peak voltage into a digital signal, and using the quantized digital signal to generate a range of maximum voltage and minimum voltage of reference voltage so as to perform a control to adjust an amplitude range of the self oscillation of the driving unit;
