An amplifier including first and second stages and a feedback loop has an output terminal coupled to a temperature compensated clipping circuit. A signal appearing at the amplifier output terminal and approaching a predetermined clipping level causes a diode in the clipping circuit to conduct. The conduction of the diode alters the feedback to the amplifier such that the altered gain of the amplifier compensates for the nonlinear conduction characteristics of the clipping diode whereby the signal is linearly translated until clipping occurs.
