Abstract: Due to the development of integrated circuits and the lack of responsiveness to existing technology, researchers are looking for an alternative technology. Quantum dot cellular automata (QCA) technology is one of the promising alternatives due to its higher switch speed, lower power dissipation, and higher device density. One of the most important and widely used circuits in digital logic calculations is the full adder (FA) circuit, which actually creates the problem of finding its optimal design and increasing performance. In this project, we designed new -combinational circuits like full adder, full subtractor, one bit magnitude comparator,4: I Multiplexer, Binary to gray code converter and Gray to binary code converter and new sequential circuits like D flip-flop in QCA technology: The proposed circuits showed excellent performance in terms of QCA evaluation parameters, especially in cell count· and cost function, compared to the other reported designs. The proposed approach was more efficient than the bestknown design, and the reason for this superiority was due to the coplanar form, without crossovers and inverter gates in the designs. The proposed designs simulated using QCA Designer Tool.
