ABSTRACT:
An operational amplifier comprising a differential circuit, an output amplifier having an input terminal connected to the output terminal of the differential circuit, a phase compensating circuit, including an inverting amplifier having an input terminal connected to the output terminal of the differential circuit, and a phase compensating capacitor connected between the output terminal of the inverting amplifier and the output terminal of the differential circuit. The signal delay time of the inverting amplifier is shorter than that of the output amplifier.
