Description
Summary:Quantum-dot cellular automata (QCA) is a promising technology for next-generation computers due to its unique features, such as very high speed, operating frequency up to terahertz, small size, power efficiency, and solving manufacture and design problems in nanoscale by exploiting quantum effects. In this study, a new reversible gate, called AG, is proposed with superior performance compared to similar gates in terms of quantum cost and delay. The proposed design can be used to implement basic logic functions. Moreover, this study presents a reversible full adder gate, which is designed and simulated based on QCA cells. The design of the proposed circuit is reversible at the logic level, and it is simulated in QCA technology using QCADesigner 2.0.3. Finally, the proposed design is compared with previous designs. The results show a significant improvement compared to other reversible circuits implemented using QCA cells. In the proposed reversible one-bit full adder gate, the cell count, occupied area, and delay are improved by 72%, 67%, and 48%, respectively.
