Double Current Limiter High Performance Voltage Level Shifter for IoT Applications

Multi supply voltage design technique is extensively used in modern VLSI designs to tradeoff energy and speed. Level shifters (LSs) are interfacing circuits that allow different voltage domains to be interfaced. This research article proposes a 0.125V- 0.325V input to 1.3V output-voltage Level Shifter that satisfies the requirements of Power, Delay, and voltage level shifting requirements of current IoT applications. The design was achieved using strong current limiters and potency pull down network. The proposed LS was implemented using 130nm technology and incurs static power of 6.6nW propagation delay of 10ns at the level shifting from 0.2V to 1.25V which is appropriate for IoT applications.
