A level shifter circuit includes a first current mirror coupled between a power terminal and a ground terminal, a second current mirror coupled between the power terminal and the ground terminal, and a level shifter. The level shifter includes a first transistor coupled to the first current mirror and a second transistor coupled to the second current mirror. The first current mirror and the second current mirror control a state of the first transistor and the second transistor.
