A Novel High Performance Dynamic Voltage Level Shifter

Level shifters are interfacing circuits, generally for Low voltage to high voltage translation Level shifters are used and high to low translation inverters are sufficient, but it needs an additional circuitry. In this paper we have presented a novel high performance Dynamic Voltage Level Shifter. It is a unique circuit will perform level-up shift, level-down shift, and Blocking. The type of shift, Level up/down is will be performed automatically based on its input voltage (VIN). The proposed dynamic voltage level shifter has designed and simulated in 90nm technology. Simulation results demonstrate that the proposed level shifter translates voltages between 0.4V to 1V and vice versa, at operating frequencies of 100 KHz, 500 KHz, and 1 MHz. It is observed that the proposed design having static power of 4.6 nW while level up, and 2.8 nW while level down operations. Level up and level down average active power is 20.9nW.
