GYRO SENSOR DRIVING APPARATUS AND METHOD FOR CONTROLLING THEREOF

摘要

Disclosed herein is a gyro sensor driving apparatus including a driving displacement signal processing unit processing a driving displacement signal input from a gym sensor and a driving signal formed by using the driving displacement signal to the gym sensor, a sensing signal processing unit converting a sensing signal input from the gyro sensor into a voltage signal and subsequently detecting a direct current (DC)-type gyro signal value through a demodulation process (mixing) using the driving displacement signal; and a quadrature signal correcting unit detecting a DC-type quadrature signal value and subsequently applying a DC-type correction signal corresponding to an integrated value of the quadrature signal value to the gyro sensor.

1. A gyro sensor driving apparatus, comprising:
a driving displacement signal processing unit converting a driving displacement signal input from a gyro sensor into a voltage signal, phase-shifting the converted driving displacement signal, and applying a driving signal formed by using the phase-shifted signal to the gyro sensor; a sensing signal processing unit converting a sensing signal input from the gyro sensor into a voltage signal and subsequently detecting a direct current (DC)-type gym signal value through a demodulation process (mixing) using the driving displacement signal; and a quadrature signal correcting unit detecting a DC-type quadrature signal value through a demodulation process using the driving displacement signal which has been converted into the voltage signal and the sensing signal, and subsequently applying a DC-type correction signal corresponding to an integrated value of the quadrature signal value to the gyro sensor.
