In this paper, a dual supply level shifter is designed for robust voltage shifting from sub-threshold to above threshold domain using high voltage CMOS technique. High voltage CMOS is an effective circuit level technique that improves the performance and design by utilizing high threshold voltage. In this minimum input voltage, attainable while maintaining robust operation is found to be around 180mV, at maximum frequency of 1MHz. The level shifter employs an enable/disable feature, which allowing for power saving when the level shifter is not in use.
