AMPLIFIER ARRANGEMENT WITH VERY LOW DISTORTION

摘要

This circuit has impedance network including auxiliary amplifier associated with another amplifier impedance network. The low distortion the amplifier circuit comprises (a) an amplifier (1), which has an inverting input(2), a non-inverting input(4), and an output(3); (b) the first impedance(5), which is coupled between the output(3) and the inverting input; (c) and a second impedance(7), which is coupled between an input terminal(6) of the amplifier arrangement and the inverting input. The gain of the amplifier arrangement is independent of the gain of the amplifier and corresponding to the ratio of the impedance values of the first and second impedances to produce an amplifier with a very low distortion.
