Abstract

PURPOSE: To reject a distortion to be generated, by comparing a signal inputted to a voltage amplifying stage with an output of a current amplifying stage of the next stage, generating a component in opposite phase with a distortion component generated at a current amplifying stage and applying it to the input side of a current amplifying stage.
CONSTITUTION: An output of a voltage amplifier 1 is applied to the input of a current amplifier 2 of voltage gain. An original signal inputted to a voltage amplifier 1 is applied to a noninverting input terminal of a comparator 3 and an output of the amplifier 2 is applied to an inverting input terminal after level matching with a resistor. Thus, a distorted component included in the signal applied to the inverting input terminal is appeared at the output side of the comparator 3. The output of the comparator 3 is in opposite phase with the distorted component generated in the current amplifier 2. When this output is applied to the input side of the current amplifier 2, the distorted component is cancelled and the output of the current amplifier 2 has finally no distortion.
