Design of Voltage Level Shifter with Wide-Range Conversion for Multi-Supply Design Applications

Abstract

This paper introduces a high-efficiency, minimal power, and rapid voltage conversion over a wide operating range level shifter. The circuit comprises leakage suppression transistors to eliminate standby power dissipation. For improved switching speed, a LVT is employed in the pull-down network, thereby providing a fast fall transition. A threshold voltage hysteresis transistor also improves the pull-up stage, which aids in the fast and full charging of internal nodes, thereby addressing signal swing issues. The circuit is performed at schematic level in a 45nm process, and experimental results show an average power of 1.04nW when it is converting from 200mV to 1.2 V. the level shifter has an average signal delay of 17.77 ns transition. And the proposed circuit have better efficiency 87% compared with remaining existed methods. The circuit achieves voltage transforms from 200mV to 1.2 V, thereby making it especially well-suited for low-power applications and multi supply voltage systems.
