Figure 5: OUT to IN operation in proposed bi-directional level shifter. Voltage range : 0.9v to 1.32v & 1.32v to 0.90v Models – best, worst, typ, bpwn,wnwp. Timing parameters are measured at wcs, 150C ...

All this leads to significant increases in power consumption and die size. The proposed circuit is a single supply level shifter to translate the signal from one power domain to another power domain.
