Abstract
In an output amplifier stage of an operational amplifier circuit, the first p-well of the first nMOSFET and the second p-well of the second nMOSFET are connected to the fourth node. Further, the first n-well of the first pMOSFET and the second n-well of the second pMOSFET are connected to the fifth node. At least one of the fourth node and the fifth node is connected to an output terminal VOUT.
