Abstract

PURPOSE: To eliminate distortion with a simple constitution, by inverting and amplifying the output of a preamplifier, feeding back the output negatively, subjecting the output of the preamplifier to noninversion amplification and adding the output of noninversion amplification and the output of inversion amplification.
CONSTITUTION: An input signal is amplified by a differential amplifier 3, and the inversion output is amplified by a main amplifier 4. The signal including an error generated by the main amplifier 4 at this time is fed back to the differential amplifier 3 negatively. Then, the noninversion output of the differential amplifier 3 is amplified by an auxiliary amplifier 10. The output including the error of the main amplifier 4 and the output of the auxiliary amplifier 10 are so added by a voltage transformer 6 that the error is cancelled.
