Abstract

<abstract abstract-type="author" id="ab0005"> <title id="sect0005">Abstract</title> <sec> <p id="sp0060">This paper presents two novel low-voltage level shifter designs: one based on cross-coupled PMOS transistors and the other using current mirror structure. These two level shifters are designed to address the problems of the existing state-of-the-art level shifters. Simulation at 65 nm shows that both of the proposed level shifters achieve significantly better performance (up to 12×) and energy consumption (up to 8×) than the state-of-the-art level shifters with similar or less area consumption while operating from near-threshold to super-threshold region, making them optimal for level shifting in low-power systems with multiple scalable voltage domains.</p> </sec> </abstract>
