ABSTRACT:
In an amplifier including an AC amplifier, its operation level shifts according to input waveforms. When a positive input signal is, for example, inputted, the circuit feeds out a synthesized signal to the amplifier in which signal a positive and negative portions are symmetry and have a time difference. The circuit compensates an operating level of the amplifier so that it amplifies a small signal to keep always a zero level of the signal being constant in spite of various signal waveforms and amplitudes whereby a linearity of the amplifier is improved and fluctuations of a dynamic range thereof are eliminated.
