A method and apparatus for high-speed clipping and recovery in an amplifier circuit is disclosed. In one embodiment, a circuit includes an amplifier configured to amplify an incoming signal. The amplifier includes inverting and non-inverting inputs, and is configured to provide a differential output. An output limiting circuit is coupled across the differential output, and is configured to limit an amplitude of an output signal provided on the differential output responsive to an input signal exceeding a first amplitude threshold. An input limiting circuit is coupled between the inverting input and the non-inverting input of the amplifier. Responsive to the input signal exceeding a second amplitude threshold (greater than the first), the input limiting circuit is configured to limit the amplitude of the output signal.
