ABSTRACT:
In an automatic gain control (AGC) circuit for controlling a preceding gain control unit and a following gain control unit, the AGC circuit according to the present invention includes at least a comparison unit, a first gain control signal output unit and a second gain control signal output unit. The comparison unit compares a signal level from the following gain control unit with a reference value. The first gain control signal output unit outputs a first gain control signal to the following gain control unit in response to an output signal obtained as a result of comparison in the comparison unit. The second gain control signal output unit outputs a second gain control signal to the preceding gain control unit. Further, the second gain control signal has a time constant longer than that of the first gain control signal output unit, in response to the output signal obtained as the result of comparison in the comparison unit.
