Abstract
An operational amplifier includes an operational amplifier circuit having at least one output node and an output stage coupled to the output node, the output stage containing an output and first MOS transistor employed in a common source amplifier mode, a frequency compensation capacitor coupled between the output of the output stage and the gate of the first transistor circuit by means of a second MOS transistor employed in a common gate amplifier mode. The other node of the capacitor and the output of the output stage are coupled to the amplifier output node with a resistor.
