An operational amplifier includes a differential amplifier input stage that supplies an operating current to a differential pair, the differential amplifier input stage including a first transistor having a first polarity, a push-pull amplifier output stage that includes a second transistor having the first polarity, and a third transistor having a second polarity, the second transistor and the third transistor being connected in series, and a capacitive element that connects a gate of the first transistor and a gate of the second transistor.
