Abstract
A non-linear amplifier is disclosed including an amplifying transistor for amplifying an input signal, an output amplified signal being derived from the amplifying transistor. A series of PN junctions is provided to supply a determined bias voltage to the amplifying transistor. An emitter-follower stage, comprised of at least one emitter-follower transistor amplifier, is connected to an input of the amplifying transistor for compensating the bias voltage applied thereto. In one embodiment, the input signal is amplified by a power of n wherein n PN junctions are connected in parallel with (n-1) emitter-follower transistor amplifiers. The input signal is supplied through the (n-1) emitter-followers to the base electrode of the amplifying transistor. In an alternative embodiment, the input signal is amplified by a power of 1/n wherein (n-1) PN junctions are coupled to the emitter electrode of the amplifying transistor and (n-1) emitter-follower transistors are connected in cascade to the base electrode of the amplifying transistor. In this latter embodiment, an output transistor is connected to the output of the emitter-follower stage.
