ABSTRACT: Emerging quantum-dot cellular automata (QCA) technology promises new opportunities for efficient digital computation by replacing traditional transistor-based designs. Many contemporary techniques can inherently realize majority-of-three (MAJ) gates, which can be employed to build efficient exclusive-OR (XOR) gates, despite the existence of more direct XOR designs with enhanced physical properties. This study proposes novel multi-digit binary coded decimal (BCD) adder designs that leverage three-input exclusive-OR (XOR3) and MAJ gates for optimal implementation......
Key Word: Quantum-dot Cellular Automata (QCA), Majority-of-three (MAJ) Gates, Exclusive-OR (XOR3) Gates, Binary Coded Decimal (BCD) Adder, Area-Delay Product.
