Disclosed is a feedback-type amplifier circuit including feedback-type charging means(11), which operates as a voltage follower, having a differential stage(21) which receives an input-terminal voltage (Vin) and an output-terminal voltage(Vout) as differential inputs and charging means(31) for performing a charging operation at the output terminal based upon an output from the differential stage(21); and follower-type discharging means(41) 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. <IMAGE>
