Abstract:
A driver circuit comprising:a follower transistor and a first switch connected serially between an output terminal and a first power supply; a first current source and a second switch connected serially between the output terminal and a second power supply; and a bias circuit for supplying the follower transistor with an input bias voltage based upon an input signal voltage, wherein said first switch is turned on at one timing in a data output interval, thereby causing said follower transistor to perform a follower operation to drive the output terminal voltage to the vicinity of a certain voltage approximately equal to the input signal voltage, said second switch is turned on at a timing subsequent to said one timing, thereby placing both said first and second switches in the ON state, and the output terminal voltage is driven to said certain voltage from said subsequent timing onward for a remainder of said data output interval.
