PURPOSE: A boost operational amplifier is provided to operate the stable driving operation by reducing deviation and shot current about the dead zone. CONSTITUTION: A differential amplifier(410) amplifies the inputted differential voltage. In order to supply the current flowing in a first output node of the differential amplifier to each of a second node and first node, a first mirror ring segment(M3, M9, M7) performs the mirroring operation. In order to supply the current flowing in a second output shift of the differential amplifier to each of the second node and the first node, a second mirror ring segment(M4, M5, M6, M10, M8) performs the mirroring operation. |
