ABSTRACT:
An amplifier (1) of improved linearity has a predistortion, bipolar junction device (4), and a transistor (2) on an input side of the amplifier (1), the bipolar junction device (4) being smaller in size than the transistor (2), and having its bipolar junction of opposite polarity with that of the transistor (2), to cancel distortion in an output of the first stage transistor (2).
