Abstract
An operational amplifier having a differential amplifier section, a level shifting section, an output section and a bias section. In the operational amplifier, the bias section senses any changes in the power voltage and controls the level shifting of the level shifting section with the sensed change in the power voltage so as to remove an offset component in the output voltage of the differential amplifier section which arises from the power voltage change.
