A New 5-Input Molecular Exclusive-OR Gate Based on Benzene Ring and Carbon Nanotube FETs

摘要

One of the main logic gates which is very useful in arithmetic circuit design is exclusive-OR (XOR). Optimizing and improving the efficiency of exclusive-OR (XOR) and exclusive-NOR (XNOR) logic functions has a significant impact on performance of larger arithmetic and logic circuits. On the other hand, using molecular electronics is one of the most promising solutions for the future of nanoelectronics. In this paper a novel 5-input molecular XOR circuit based on hybrid architecture of P-type benzene ring and N-type Carbon Nanotube FETs is presented. The area occupied by this design would be far less than the conventional designs. The results of the simulations, conducted using Synopsys HSPICE show about 53% and 44% improvements in terms of power and PDP, respectively, as compared with its purely CNFET-based counterpart design.
