APPARATUS FOR DRIVING GYRO SENSOR AND METHOD FOR CONTROLLONG THEREOF

摘要

Disclosed herein is an apparatus for driving a gyro sensor, the apparatus including: a driving unit, an automatic gain control unit, and a first signal converting unit, wherein the driving unit transmits data for a phase value or amplitude value so that an operation of a control gain for an amplitude or phase of a driving mass resonance of the automatic gain control unit may be performed depending on a preset ratio.

1. An apparatus for driving a gyro sensor, the apparatus comprising:
a driving unit detecting an amplitude value and a phase value of a driving mass resonance from a driving displacement signal of a gyro sensor and transmitting data for the phase value or amplitude value; an automatic gain control unit differentially performing an operation of a control gain for an amplitude or phase of the driving mass resonance depending on a preset ratio so that after converting the phase value or amplitude value transmitted from the driving unit into a digital value, the digital value converges on a preset target value; and a first signal converting unit converting the control gain into an analog value and transmitting the analog value to the driving unit.
