Abstract
In one embodiment, a signal-processing apparatus for generating an amplified output signal based on an input signal is provided. The apparatus comprises: an amplifier configured to generate the output signal, wherein the amplifier is configured to receive a supply voltage; and a limiter configured to inhibit increases in the input signal power level from being applied to the amplifier, wherein the limiter comprises: a variable attenuator configured to selectively attenuate the input signal before being applied to the amplifier; wherein the limiter integrates over a voltage difference between a current measure of attenuated input signal power level and a limiter threshold level to control a level of attenuation applied by the variable attenuator to the input signal.
