An automatic gain control (AGC) system includes at least one variable-gain component having a controllable gain over a gain control range and a sensor for sensing an amplitude of a signal from the at least one variable-gain control component. The sensor may have an operating window based upon the signal that is smaller than the gain control range of the at least one variable-gain control component. The AGC system may also include a controller responsive to the sensor for controlling the at least one variable-gain component according to coarse and fine gain values to set the amplitude of the signal within the operating window of the sensor.
