An operational amplifier employing complementary MOSFET transistors includes first and second differential amplifiers respectively employing complementary conductivity type transistors. The input connections of the first and second differential amplifiers connect in parallel to receive the same input signal, the common-mode voltage of which may vary to and include first and second supply potentials. First and second current mirror amplifiers, respectively employing complementary conductivity type transistors, have input connections to which first and second output connections of the first differential amplifier respectively connect, and have output connections connected to an output terminal. Third and fourth current mirror amplifiers, respectively employing complementary conductivity type transistors, have input connections to which first and second output connections of the second differential amplifier respectively connect, and have output connections connected to the output terminal.read more
