    Abstract: An apparatus for driving a gyro sensor includes a gyro sensor, an analog circuit, a signal converter, and a digital automatic gain controller. The gyro sensor includes at least one driving mass. The analog circuit detects an amplitude value or a phase value of resonance of the driving mass from first and second driving displacement signals output from the gyro sensor. The signal converter converts the amplitude value or the phase value into a digital value. The digital automatic gain controller outputs a control gain for controlling a signal driving resonance of the driving mass based on a selected one of a phase or amplitude of resonance of the driving mass, so that a selected one of the amplitude value and the phase value input from the signal converter is converged to a preset targeted value.
