Abstract
A level shifter includes: a first buffer amplifier transferring a preset reference voltage to a first output terminal; a second buffer amplifier connected in parallel to the first buffer amplifier and transferring an input voltage to a second output terminal; a positive feedback amplifier connected in parallel to the first buffer amplifier and the second buffer amplifier, and amplifying the input voltage by a preset gain to transfer the amplified input voltage to a third output terminal; and a level regulation unit regulating levels of output signals of the first buffer amplifier, the second buffer amplifier, and the positive feedback amplifier and providing the regulated output signals to a common output node.
