Abstract
Level shifters are disclosed for high performance sub-micron IC designs. One embodiment is a level shifting device that comprises a first input circuit that toggles a first internal signal between a logical zero of a first voltage range and a logical one of a second voltage range based on an input data signal and an output data signal, and a second input circuit that toggles a second internal signal between a logical zero of the second voltage range and a logical one of the first voltage range based on the input data signal and the output data signal. An output circuit of the device toggles the output data signal between a logical zero of the second voltage range and a logical one of the second voltage range based on the first internal signal, the second internal signal, and a compliment of the input data signal.
