Abstract
In an integrated circuit, a voltage level shifter transitions an input signal at a first voltage level to an output signal at a second voltage level. The voltage level shifter generally includes switching elements, such as transistors, that control switching the output signal between logical zero and logical one values. The switching elements have a maximum voltage below which they can operate. The maximum voltage is less than the second voltage level. The voltage across the switching elements is limited to less than the maximum voltage.
