Abstract
A low-distortion amplifier circuit which comprises a transistor amplification circuit composed of an amplification transistor and an input terminal, an output terminal and a power source terminal, a first resistor connected between the input terminal and the amplification transistor, a second resistor connected between the output terminal and the power source terminal, and n pieces of forward direction diode elements which are made of transistors with the same characteristic as that of the amplification circuit, have their collectors and bases being shorted, and are connected in series together with the second resistor between the output terminal and the power source terminal. The first and second resistors are arranged to have resistors so that the proportion between these two resistors multiplied by the amplification rate of each transistor equals the number n of forward direction diode elements.
