The first resistance coupled to the circuit input to work with a transistor as a voltage divider for an input signal, for an amplifier connected to the resistance. A damping and/or rectifying component is coupled to the circuit output, between the amplifier and the base of the transistor. A second resistance is coupled between the emitter of the transistor and earth. This second special resistance functions to produce a low distortion performance. In parallel with the amplifier there is coupled a circuit branch in which a diode, connected to the circuit output, is series coupled with a transistor, which in turn is connected to a point between the resistance and the amplifier. |
