Abstract

A level shifter circuit includes a level shifter unit and a first controlling unit. The level shifter unit has an input node for receiving an input signal having a predetermined level, an output node for outputting an output signal having a desired level and a complementary output node for outputting a complementary output signal complementary to the output signal. The first controlling unit is coupled to the level shifter unit and has a first transistor coupled between the complementary output node and a first control node for receiving a first control signal and a second transistor coupled between the input node for receiving the input signal and a ground.
