Abstract
Scaling challenges and limitations of conventional silicon transistors have led the designers to apply novel nano-technologies. One of the most promising and possible nano-technologies is CNT (Carbon Nanotube) based transistors. CNFET have emerged as the more practicable and promising alternative device compared to the other nanotechnologies.  This technology has higher efficiency compared to the silicon-based MOSFET and is appropriate for high-frequency applications. Full Adder cell is the  essential core and the building block of most arithmetic circuits and is placed on most parts of their critical paths .In this paper, power-efficient CNFET (Carbon Nanotube Field Effect Transistor) based Full Adder cell is proposed. This design is simulated in several supply voltages, frequencies and load capacitors using HSPICE circuit simulator. Considerable improvement is achieved in terms of power and PDP (Power-Delay-Product) in comparison with other classical CNFET-based designs, in the literature. Our proposed Full Adder can also drive large load capacitance and works properly in low supply voltages.
