ABSTRACT:
An amplifier device comprises an amplifier circuit, a differential amplifier for amplifying the difference between an input and an output of the amplifier circuit with an amplification degree which is substantially equal to one, and an addition circuit for adding an input signal to an output signal of the differential amplifier circuit and applying the result of addition to the input terminal of the amplifier circuit. Thereby, the distortion of the amplifier circuit is eliminated, and the input signal and the output signal coincide with each other. Hence, by applying the technical concept of the invention to an amplifier with a feedback loop, the distortion factor can be reduced without the increasing of the amount of feedback.
