Abstract
The overdrive amplifier may include: a differential input circuit arranged by connecting, in a folded-cascode style, input transistors supplied with an input signal at gates, and feedback input transistors accepting the feedback of an output signal at respective gates; a current mirror load having mirror input current paths connected to current paths of the feedback input transistors, and mirror output current paths connected to current paths of the input transistors; an output circuit accepting the input of output control signals from the mirror output current paths of the current mirror load; and an overdrive circuit which causes bias currents of directions which boost an output of the output circuit, depending on the output control signals, to pass through the current mirror load based on the output control signals in an overdrive period.
