QCA technology is an emerging and promising technology for implementation of digital circuits in nano-scale. The comparator circuits play an important role in digital circuits. In this work, a new and efficient coplanar 1-bit comparator circuit is proposed and evaluated in the QCA technology. The designed coplanar 1-bit QCA comparator circuit is constructed based on majority gate, XNOR gate and inverter gate that are designed carefully. The functionality of the designed coplanar 1-bit QCA comparator circuit is verified by using QCADesigner version 2.0.3. The obtained results indicate that the designed 1-bit QCA comparator circuit requires 0.03 µm 2 area and 38 QCA cells. It also has 0.5 clock cycles delay. The comparison demonstrates that the designed QCA comparator circuit provides improvements in comparison with other QCA comparator circuits in terms of effective area, cell count, and delay as well as cost.

Quantum-dot cellular automata (QCA) is inventive nanotechnology that suggest lesser size, lesser power consumption, with more rapid speeds and deliberated as a clarification to the scaling difficulties with CMOS technology. Physical bounds of CMOS for instance the effects of quantum and the limits of technologies like power dissipation obstruct the motion of microelectronics using consistent circuit scaling. In this paper, a 1-bit binary magnitude comparator circuit is proposed that takes down the count of QCA cells related to the previously reported design’s cell numbers. The proposed course of study involves just around 29 % of the total area as compared to the preceding design with the lesser speed and clocking cycle performance and energy dissipation also. QCA designerE tool is used for simulation and finding the parameters also. The projected magnitude comparator also compares the metrics result with some of the other preceeding patterns.
