ABSTRACT:
An apparatus having an electronic amplifier with signal gain dependent bias. The electronic apparatus includes the amplifier and a bias state control circuit. The electronic amplifier has a signal gain and a bias state. The signal gain is adjustable to either of at least two different signal gain settings, and the bias state is adjustable to either of at least two different bias state settings. The bias state control circuit has capability of adjusting the bias state setting of the amplifier based upon the signal gain setting to which the amplifier is adjusted.
