Abstract:
Disclosed are level shifters and methods of performing level shifting. In one embodiment, a level shifter is disclosed comprising an input, cross-coupled/latch circuitry, a first reference node, a second reference node, and output circuitry coupled between the cross-coupled/latch circuitry and an output, wherein the output circuitry sets the output signal to high based on rising edge of a second reference node and sets the output signal to low based on the rising edge of the first reference node. Further, the first reference node and the second reference node are symmetric nodes having signals that are inverse to each other.
