A method and system for providing automatic gain control for a differential amplifier are provided. An impedance network is set to have a first impedance that corresponds to a first gain for a differential amplifier, which amplifies an input signal by the first gain. Once the amplified input signal is greater than a first threshold voltage, the impedance network is set to have a second impedance that corresponds to a second gain for the differential amplifier, which amplifies the input signal. Once amplified input signal is greater than a second threshold voltage and a predetermined period has lapsed, the impedance network is reset to have the first impedance that corresponds to a first gain for the differential amplifier.
