Patent ID: 8490484

Claim:
An apparatus for driving a gyroscope sensor, the apparatus comprising: a detector configured to detect a detecting voltage corresponding to deformation of a gyroscope sensor due to vibrations generated by a first driving voltage supplied through at least one driving electrode of the gyroscope sensor and a Coriolis force; a phase shifter configured to shift the detecting voltage from the detector by a preset phase to generate a second driving voltage, in order to meet oscillation phase conditions; an inverter configured to invert the second driving voltage from the phase shifter to generate an inverting voltage, in order to stop the driving of the gyroscope sensor; a selector configured to select any one of the second driving voltage from the phase shifter and the inverting voltage from the inverter; and an amplifier configured to amplify the selected second driving voltage or inverting voltage with a preset gain and to supply the amplified second driving voltage or inverting voltage to the at least one driving electrode of the gyroscope sensor, in order to meet oscillation amplitude conditions.
