In the near future, it is expected that the CMOS technology reaches to the end of its road map because of many serious challenges such as short channel effect, impurity variations, high cost of lithography and more importantly, the heat. So, many technologies such as Single Electron Transistor (SET), Resonant Tunneling Diode (RTD), and Carbon Nano tube Field Effect Transistor (CNFET) and Quantum dot Cellular Automata (QCA) have been emerged to solve the mentioned problems. According to the international technology road map for semiconductors (ITRS) report which offers an accurate summary of future technologies, QCA is one of the promising future solutions. It has been found that the existing 3-input XOR gate are not only efficient and the structures are not well optimized in this way. To overcome this, and try to find new progressive structural optimization to generate desired full adder result. We have proposed a new low-complexity repulsive geometry structural gate DUT, which consumes less Area compared to prior designs. To evaluate the usefulness of proposed design a new one bit full adder circuit is presented. Our design achieves good improvement in cell count and consumes less area in comparison to the best single layer design. QCADesigner tool is used to validate the layout of the proposed designs. The usefulness of exhibited plans has been performed in QCADesigner form 2.0.3
