• The large amount of secondary effects in complementary metal–oxide–semiconductor technology limits its application in the ultra‐nanoscale region. Circuit designers explore a new technology for the ultra‐nanoscale region, which is the quantum‐dot cellular automata (QCA). Low‐energy dissipation, high speed, and area efficiency are the key features of the QCA technology. This research proposes a novel, low‐complexity, QCA‐based one‐bit digital comparator circuit for the ultra‐nanoscale region. The performance of the proposed comparator circuit is presented in detail in this paper and compared with that of existing designs. The proposed QCA structure for the comparator circuit only consists of 19 QCA cells with two clock phases. QCA Designer‐E and QCA Pro tools are applied to estimate the total energy dissipation. The proposed comparator saves 24.00% QCA cells, 25.00% cell area, 37.50% layout cost, and 78.11% energy dissipation compared with the best reported similar design.
