ABSTRACT:
A gain control at the input monitors an input signal and a supply voltage, which drives an output. The gain control adjusts the gain to compress the input signal when the supply voltage decreases in magnitude and/or the input signal is of such magnitude to cause the supply voltage to decrease.
