Abstract
An operational amplifier comprises a differential amplifying circuit and an output circuit. The differential amplifying circuit comprises a pair of input transistors having control terminals connected to an inverting input terminal and a non-inverting input terminal, respectively. The output circuit is connected to the differential amplifying circuit for amplifying an output signal of the differential amplifying circuit and generating an amplified output from its output terminal. In this operational amplifier, the input transistors are bipolar transistors and other transistors are MOS transistors.
