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 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 divider achieves 5.5, 18.8, and 33.1% reductions in cell count, latency, and area, respectively, compared to the existing designs.
