Abstract
The base of a transistor constitutes the input of an amplifier arrangement, to which an input signal may be applied. The emitter of this transistor is coupled to the negative power-supply terminal by means of a first resistor. The collector of this transistor is coupled to the input terminal of a first current multiplier circuit, whose output terminal is connected to the output of the amplifier arrangement and to the emitter of the transistor by means of a second resistor. The first current multiplier circuit further has a sum terminal which is connected to the positive power-supply terminal. In order to reduce the distortion in the arrangement it further comprises a second current multiplier circuit whose input terminal is connected to the collector of the transistor and whose sum terminal is connected to the input terminal of the first current multiplier circuit. The output of the second current multiplier circuit is connected to the negative supply terminal of the transistor.
