“…In nanotechnology, quantum‐dot cellular automata (QCA) is a promising nano‐device for replacing field‐effect transistor (FET) architectures. Scaling to the CMOS circuit has many physical limits and inherits problems 1–3 . Thus, an alternative device is essential, and QCA serves these opportunities.…”

This article describes designing a low‐power novel circuit for overflow detection in two's complement arithmetic operations. The quantum‐dot cellular automata (QCA) is employed to achieve the nanoscale design. For designing the circuit of the proposed arithmetic overflow detector, a new layout of the QCA full adder is utilized. Two different designs of arithmetic overflow detectors are outlined in this article. The designs are compared based on latency, cell count, and device area. Based on the comparison, the best design for an arithmetic overflow detector is presented. The circuit cost for all the designs is also shown in this work. Besides, thermal power's effect on the output cell's polarization has also been investigated. The power dissipation of all proposed QCA layouts is estimated.
