In this paper, by using the Carbon Nanotube Field Effect Transistor (CNFET), which is a promising alternative for the MOSFET transistor, two novel energy-efficient Full Adders are proposed. The proposed full adders show full swing logic and strong output drivability. The first design uses eight transistors and nine capacitors and the second design utilizes three capacitors less than the first design. Simulations, carried out using HSPICE based on the Stanford University CNFET model at 0.6V and 0.9V supply voltages, demonstrate the efficiency of type proposed circuit parameters such as delay, power and powerdelay product.
