Authors(3) :-Waseem H. Wani, Mohammad T. Banday, Saroj Patel

Quantum-dot cellular automata (QCA) is a novel nanotechnology which promises molecular digital circuits with ultra-high clock frequencies, alternative solution to replace to replace the conventional CMOS technology which is reaching their physical limits. Despite a lot is still needed for the large scale utilization of the technology, there has been serious effort in digital design implementation in QCA. In this paper, a new architecture of Half and Full subtractor based on the QCA is proposed. The benefit of optimal FNZ universal gate is taken in demonstrating these arithmetic units, which has already designed based on the QCA. The design helps to reduce the complexity, then the conventional subtractors based on the QCA, in terms of covered area, count of the cells, and delay. The proposed subtractors are designed and simulated using QCA Designer tool version 2.0.3.
