Abstract: A level shifter includes a first input having low voltage switches, and is configured to receive an input voltage and to generate a second voltage which varies between a first low voltage and a first high voltage. The level shifter also includes a first output having medium voltage switches, and is configured to receive the second voltage and to generate a third voltage which varies between the first low voltage and a second high voltage. The level shifter also includes a second input having medium voltage switches, and is configured to receive the third voltage and to generate a fourth voltage which varies between a second low voltage and the second high voltage. The level shifter also includes a second output having medium voltage switches, and is configured to receive the fourth voltage and generate a fifth voltage which varies between the second low voltage and a third high voltage.
