Power management is of increasing concern and challenge to SOC and product designer. Power Gating (PG) is now well understood as a technique for reducing static leakage power when circuits are idle In the IOT applications, Level shifters (LS) are used to transport digital signals from the near-threshold voltage level to the actual supply voltage level when interfacing the near-threshold domain and the nominal voltage domain. The LS should be quick enough to meet needs while keeping transition energy and static power as low as possible in order to reduce overhead. For this, we are proposing the double current limiter level shifter with Power Gating Technique which reduces the power consumption by preventing the supply directly connected to the circuit. At the power supply, two transistors were connected in parallel to obtain the design. Level Shifter that meets the requirements of contemporary IOT applications for power, delay, and voltage level shifting. The proposed Level Shifter was implemented in 45nm technology using Tanner EDA tool.
