Apparatus for driving inertial sensor and controlling method of the same

Abstract

Disclosed herein is an apparatus for driving an inertial sensor, the apparatus including: at least one inertial sensor including a driving mass; an analog circuit unit detecting an amplitude value and a phase value of a driving mass resonance from a driving displacement signal of the inertial sensor; a first signal converting unit converting the amplitude value and the phase value into a digital value; a digital automatic gain control unit generating a control gain for controlling an amplitude or phase of the driving mass resonance so that the digitalized amplitude value or the phase value converges on a preset target value; and a second signal converting unit converting the control gain into an analog value and transmitting the analog value to the analog circuit unit, wherein the analog circuit unit applies a driving signal having the control gain reflected thereto to the inertial sensor.
