Patent abstract
A high-speed, area-efficient level shifter includes transistors having a variety of oxide thicknesses. The level shifter has a protection circuit stage, and a current mirror stage that allows the level shifter to perform over a wide voltage range at a high frequency. The level shifter maintains rise time, fall time, and duty cycle over a wide range of input and output voltage levels.
