The present invention discloses a device and method for generating an auto gain control signal. When a gain of an input signal is very different from a wanted gain, an increase of an integral value is prevented by repeatedly resetting an integrator. Especially, the device can sensitively respond to a fast moving substance on a channel, by reducing a repeated reset period of the integrator. At the same time, it is possible to minimize reduction of the performance of a receiver due to a residual jitter generated by the shortened period. As a result, the receiver has an improved performance in regard to the gain variations of the whole channels.
