Abstract
Disclosed is a feedback-type amplifier circuit including feedback-type charging means, which operates as a voltage follower, having a differential stage which receives an input-terminal voltage and an output-terminal voltage differentially as inputs and charging means for performing a charging operation at the output terminal based upon an output from the differential stage; and follower-type discharging means for performing a discharging operation at the output terminal by follower operation of an active element in accordance with a voltage difference between the input-terminal voltage and the output-terminal voltage.
