A level shifter circuit a first transistor connected between a power source terminal of the level shifter circuit and an output terminal of the level shifter circuit, the first transistor being configured to transmit, in response to a first signal and a second signal, a power source voltage applied from the power source terminal to the output terminal, the first signal being received from an input terminal of the level shifter circuit through a first gate of the first transistor, the second signal being received through a second gate of the first transistor, and a second transistor connected between a ground terminal of the level shifter circuit and the output terminal, the second transistor being configured to transmit a ground voltage from the ground terminal to the output terminal in response to a gate signal received through a gate of the second transistor.

Level shifter circuit

Provided is a single input level shifter. The single input level shifter includes: an input unit applying a power voltage to a first node in response to an input signal and applying the input signal to a second node in response to a reference signal; a bootstrapping unit applying the power voltage to the second node according to a voltage level of the first node; and an output unit applying the input signal to an output terminal in response to the reference signal and applying the power voltage to the output terminal according to the voltage level of the first node, wherein the bootstrapping unit includes a capacitor between the first and second nodes, and when the input signal is shifted from a first voltage level to a second voltage level, the bootstrapping unit raises the voltage level of the first node to a level higher than the power voltage.
