Abstract
This paper proposes CMOS- and Carbon Nanotube FET (CNFET)-based high-speed level-shifter circuits. The proposed level-shifter designs make use of the Low-Threshold-Voltage Transistors and High-Threshold-Voltage Transistors devices available in the CNFET and 45 nm CMOS technologies, to significantly reduce the propagation delays and transistor count. The performance of the proposed level-shifters has been compared with the conventional level-shifter and other state-of-the-art level-shifter designs reported in the literature. The proposed level-shifters operate significantly faster (98% lower prorogation delays) as compared to the benchmarked level-shifter designs, and a reduction of 95% in Power Delay Product can be achieved.
