Abstract: In nanotechnologies, quantum-dot cellular automata (QCA) offer promising and attractive features for nano-scale computing. QCA effectively overcomes the scaling shortfalls of CMOS technology. One of the variants of QCA is 4 Dot 2 Electron QCA which is well explored and researched. The main concentration of this study is on 2 Dot 1 Electron QCA, an emerging variant of QCA. A novel and efficient XOR gate based on 2 Dot 1 Electron QCA is designed. Moreover a comparator using the proposed novel XOR gate is presented in this present scope. The proposed architecture is justified using a well-accepted standard mathematical function based on Coulomb’s law. Energy and power dissipation of the architecture are analyzed using different energy parameters. AS the compactness of proposed design is 76.4% the design met high degree of compactness and better efficiency.
