Abstract
An operational amplifier with frequency compensation circuit is provided. The operational amplifier includes first/second differential amplifying pairs and first/second frequency compensation circuits. The first differential amplifying pair includes a first differential gain circuit and a first differential input pair, and the second differential amplifying pair includes a second differential gain circuit and a second differential input pair. The first/second frequency compensation circuits respectively include a resistor and a capacitor that is serially connected to the resistor. One end of the first frequency compensation circuit connects to a point in the transmission path, which transmits positive signal, between the first differential gain circuit and the first differential input pair, and another end connects to a positive signal output terminal of the second differential amplifying pair. Further, one end of the second frequency compensation circuit connects to a point in the transmission path, which transmits negative signal, between the first differential gain circuit and the first differential input pair, and another end connects to a negative signal output terminal of the second differential amplifying pair.
