Abstract

This brief presents a fast and power-efficient voltage level shifting circuit capable of converting extremely low levels of input voltages into high output voltage levels. The efficiency of the proposed circuit is due to the fact that not only the strength of the pull-up device is significantly reduced when the pull-down device is pulling down the output node, but the strength of the pull-down device is also increased using a low-power auxiliary circuit. Post layout simulation results of the proposed circuit in a 0.18-μm technology demonstrate a total energy per transition static power dissipation and a propagation delay for input frequency of 1 MHz The entire work is carried out in the 180nm technology of T spice tool is used for time delay, The resulting analysis shows that the proposed method is better than conventional CMOS
