Carbon Nano Tube (CNT) multiplexers for multiple-valued computing

Abstract

Novel two types of Carbon Nano Tube (CNT)-based multiplexers are introduced The first device is a solid-state transmission gate (t-gate) multiplexer that uses CNT as a channel in the Field Effect Transistors (FET) of both n-FET and p-FET types that are used. Because of its very small size, it has been shown that a CNT-based FET switches reliably using much less power than a silicon-based device, and thus the new device will consume less power than traditional t-gate multiplexer. The second new CNT device uses the fundamental Lorentz magnetic force from the basic laws of Electromagnetics as a switching mechanism between two conducting CNTs. The implementation of multiple-valued Galois logic using the new CNT devices is shown. Since a multiplexer is a fundamental logic block, the new devices can have a wide range of applications in a wide variety of nano circuits.
