Cross Coupled Power Effective Quick Level Shifter

A power effective and quick LS (Level Shifter) is proposed using cross couple structure. The designed LS will help to overcome the drawbacks of previous LS by utilizing cross coupled structure at the pull-up area, it will help circuit to increase its functional speed and power, energy needed for circuit is also decreased. Comparing to existing ones, the proposed LS need very low number of components to design and sizes of these components are minimized. This will help to lower the area required by LS. The advantage of proposed LS is it performs constructively when the input is lower than the Vth and offers very low delay. These simulations are performed by using LT spice tool which is of 180nm technology. The power utilization and overall delay of designed LS is 149.5nW and 23.6ns for 1 MHz and 0.4V/1.8V.
