A Novel Energy Efficient Transmission gate Voltage Level Shifter for multi VDD systems

A new design of level-up and level-down shifter for low-power and high speed applications has been presented. Level-up and level-down operations can be perform by using the new well-organized Transmission gate Voltage Level Shifter (TVLS). In this paper a novel voltage level shifter have introduced that performs level-up shift or level-down shifts. In this, the circuit watch its input logic voltages and perform leve-up shift, when its input voltage is low and level-down shift when its input voltage is high. This TVLS constantly performs level-up shift from 0.4V to 1V and level-down shift from 1V to 0.4V. The schematic design has been design and simulated using 90nm CMOS process technology. In analysis of power and delay, TVLS has level-up and level-down average power consumption is 24.7145nW and with a propagation delay of 2.053ns has obtained at 1 MHz.
