Carbon Nanotube Transistor Circuits: Circuit-Level Performance Benchmarking and Design Options for Living with Imperfections

Abstract

1D carbon nanotube FET (CNFET)-based circuits offer 4.6times faster FO4 speed and 12times energy-delay product improvement over 32nm node Si CMOS (including diameter and doping variations), provided circuits can be built that are immune to misaligned and metallic nanotubes. A design technique that guarantees correct logic operation in the presence of misaligned nanotubes is also presented.
