Abstract:
QCA has emerged as a leading nanocomputing technology and is positioned as a substitute for CMOS VLSI technology. This study presents an optimal and scalable coplanar QCA Full Adder with No-Crossover (QFANC) design using a Modified XOR gate (MXOR) structure that contains a part of the majority gate. The proposed QFANC design utilizes 13 QCA cells and is employed to efficiently design QCA Ripple Carry Adder circuits with no-crossover (QRCANC) with input sizes of 4-bit and 8-bit to demonstrate its scalability. The simulation and functional verification are performed using the QCA Designer (v2.0.3) tool. Energy dissipation of proposed designs and equivalent QFAs reported in the literature is estimated using the QCA Designer-E tool. Comparative analysis across various metrics implies that the suggested QFANC design is optimal with a reduction of 15% in area, 7% in cell complexity, and 3% in energy dissipation associated with the finest scalable QFA design reported.
