چکیده

Quantum cellular automata (QCA) is an alternative promising nanotechnology for semiconductor transistor based technology. QCA benefits from several characteristics, including high speed and low power usage, and could be employed in extremely dense structures. One of the important issues in arithmetic circuits is design of full subtractor/ full adder (FS/ FA), respectively. This paper proposed a 1-bit FS/ FA circuit on the basis of QCA technology that benefits from less cell counts compared to the best peer designs studied in the literature. As well as the mentioned feature, temperature analysis of suggested circuit indications that the presented design is tougher than previous works.
