| description | The limitations of Complementary Metal Oxide Semiconductor (CMOS) such as high-power dissipation, short channel effects, and high lithography has prompted scientists to look forward to alternatives. Many nanotechnologies were emerged and still in the competition such as Fin Field-Effect Transistor (FinFET), Carbon Nanotube Field-Effect Transistor (CNFET), Quantum-dot Cellular Automata (QCA). QCA is a new nanoelectronics technology used a new method for calculations and it is a promising technology in terms of power dissipation. In QCA, circuit complexity is depending on cell count, area and latency. For commercial purposes a universal gate is necessary, this gate can be used alone to design any Boolean function, where in CMOS technology, the NAND or NOT gates have the ability to be a universal gate. The dominant gates in QCA are the majority gate with inverter where QCA circuits cannot be designed using only a universal gate. Because the structure of the gate is important in QCA, this paper introduces a new low complexity singular block that can be used as a universal block. The proposed block can be used to form AND, OR, NOT, Exclusive-OR (XOR) and Multiplexer (MUX). So, this block not just used to design any circuit but also it can be used to form other important functions XOR and MUX to build large circuits in an optimum form. |
