Abstract
The present invention relates to a differential amplifier circuit. A differential amplifier circuit has an advantage in that it can improve a voltage drop characteristic attributable to a load current by enhancing response speed. Furthermore, the differential amplifier circuit can improve a bandwidth characteristic by reducing the quiescent current of a class AB amplifier and also improve a slew rate characteristic by adaptively changing a tail current because a signal path is diversified. Accordingly, response speed can be enhanced by an improved bandwidth characteristic, and the current driving ability can be also enhanced by an improved slew rate characteristic.
