Abstract
The physical limitations of complementary metal‐oxide semiconductor (CMOS) technology have led many researchers to consider other alternative technologies. Quantum‐dot cellular automate (QCA) is one of the nanotechnologies that is being considered as possible replacements for CMOS. In this paper, a QCA circuit for an n ‐bit non‐restoring binary array divider (NRD) is designed. The proposed divider is developed using multi‐layer and a QCA structure of the three‐input XOR function. Compared to the previously proposed QCA designs for NRD, the proposed design provides further reduction in cell count, latency, and area. The results for a 3 × 3 NRD show that the proposed design enables 14.8, 14.8, and 20.3% reductions in cell count, latency, and area, respectively. In addition, the proposed 4 × 4 divider achieves 5.5, 18.8, and 33.1% reductions in cell count, latency, and area, respectively, compared to the existing designs.
