An apparatus comprising a first amplifier circuit, a detect circuit, a control circuit and a second amplifier circuit. The first amplifier circuit may be configured to generate an amplified signal in response to an input signal. The detect circuit may be configured to generate a feed-forward signal in response to the amplified signal. The control circuit may be configured to generate a dynamic control signal in response to the feed-forward signal. The second amplifier circuit may be configured to generate an output signal in response to (i) the amplified signal and (ii) the dynamic control signal. The control circuit may be configured to control a gain of the second amplifier circuit by adjusting a magnitude of the dynamic control signal.
