APPARTUS FOR GYRO SENSOR AND CONTROLLING METHOD THEREOF

摘要

A gyro sensor driving apparatus according to the present invention comprises a driving displacement signal treatment part treating a driving displacement signal input from a gyro sensor, and applying a driving signal formed by using the driving displacement signal to the gyro sensor; a sensing signal treatment part detecting a direct current (DC)-formed gyro signal through a modulation process (mixer) using the driving displacement signal after converting the sensing signal input from the gyro sensor into a voltage signal form; and a quadrature signal compensation part detecting a direct current (DC)-formed quadrature signal, and applying a direct current (DC)-formed compensation signal corresponding to an integrated value of the quadrature signal to the gyro sensor.
