Abstract
An amplifier includes a push-up circuit and a pull-down circuit. The push-up circuit includes a first differential pair and a first driving circuit. The first driving circuit is connected to the first differential pair in a cascade manner. The first driving circuit has a common source amplifying circuit formed of a MOS (metal-oxide-semiconductor). The pull-down circuit includes a second differential pair and a second driving circuit. The second driving circuit is connected to the second differential pair in a cascade manner. The second driving circuit has a common source amplifying circuit formed of a MOS. A portion of a normal operation voltage range of the push-up circuit overlaps a portion of a normal operation voltage range of the pull-down circuit.
