Abstract: A level shifter includes an input stage circuit, a latch circuit and a transient speed-up circuit. The input stage circuit receives an input signal. The latch circuit is coupled to the input stage circuit through a first output terminal and a second output terminal, and determining steady-state levels of the first and the second output terminals according to the input signal. The transient speed-up circuit is coupled to the first and the second output terminals. When the transient speed-up circuit determines the first and the second output terminals are at the same logic level, the transient speed-up circuit accelerates the positive edge transition of the first or the second terminals.
