Abstract: Quantum-dot cellular automata (QCA) technology is one of attractive emerging technologies that are suitable for low-power, and ultra-dense digital circuit’s development. QCA Comparator plays an important role in the digital circuits. In this study, a new QCA comparator architecture is presented. This new architecture is carefully designed using three 3-input majority gates. The proposed QCA comparator architecture is simulated by using the QCADesigner tool version 2.0.3. The designed QCA comparator has 29 cells and the occupied area by circuit is 0.04 µm2. The results demonstrate that the developed QCA comparator architecture provides an improvement compared to other QCA comparator architectures in terms of the number of required cells.
