Multiplication scheme is one of the most essential factors, which is time consuming. Designers and manufacturers of processors emphasis on methods which would not only perform the multiplication scheme in a rapid manner, but would reduce the physical aspect of the design as well; hence, a reduction in power consumption. Addition is one of the fundamental factors in multiplication. Pre-designing of circuits and transistors’ levels used to be made through Metal Oxide Semiconductor Field Effect Transistor (MOSFET), but now, due to scaling and difficulties thereof, new technologies like Single Electron Transistor (SET), Quantum-dot Cellular Automata (QCA) and Carbon Nanotube Field Effect Transistor (CNFET) are introduced. Among the new technologies, CNFET has become center of attention due to similarities in electronic features in relation to MOSFET. A comparison made between CNFET with MOSFET technologies indicate that, power delay product (PDP) and power leakage can be less in nanotube transistors. Field effect transistor circuit’s simulations are accomplished through HSPICE simulator. The simulation results indicate that this proposed Three-operand Carbon Nanotube Multiplier has a better performance in comparison with the three-operand multiplication done on computers nowadays, which we call it classical multiplier in this article.
