Claim Text:
1. A gyro sensor driving circuit comprising: a charge/voltage conversion unit configured to receive a charge output from a vibration-type gyro sensor and to convert the charge output into a voltage signal; a phase converting unit configured to receive a signal from the charge/voltage converting unit and to convert a phase of the received signal; a pulse generating unit configured to receive an output signal of the phase converting unit and to output the output signal as a pulse wave; a pulse converting unit configured to convert the pulse wave output from the pulse generating unit into a pulse signal using a certain voltage level as reference so as to apply the pulse signal as a driving signal of the vibration-type gyro sensor; and a control unit configured to control the pulse converting unit to generate the pulse signal using the certain voltage level as reference, wherein the pulse converting unit comprises:
