Abstract
Disclosed herein is a gain control device of a gyro sensor driving signal, including: a gyro sensor generating a gyro signal; a driving signal supply unit applying a driving signal to the gyro sensor; and a gain control unit detecting positive and negative driving signals of the gyro sensor so as to be output as a pulse waveform and changing the pulse waveform to a resistance value corresponding to the pulse waveform to compensate for a gain of the driving signal, whereby it is possible to simply implement the circuit and reduce costs, by controlling the gain of the gyro sensor
