Summary
Nanotechnology and very large‐scale integration (VLSI) fabrication have a reflective productivity. The growth of one demands the growth of the other. In nanotechnology, quantum‐dot cellular automata (QCA) secures as the best alternative for replacement of complementary metal‐oxide semiconductor (CMOS) technology for integrated circuit (IC) fabrication. This paper presents an integration of the two domains wherein a novel ultraefficient, multioperative 3 × 3 universal reversible gate, Sadat Farah Vijay (SFV)‐QCA, is proposed and implemented in QCA technology using majority voter approach. SFV‐QCA gate is redesigned and restructured using precise QCA cell interaction for optimization. The basic logic gates are implemented using the proposed SFV‐QCA gate to validate its universality. All the 13 standard Boolean functions are implemented using SFV‐QCA to demonstrate its multioperation nature. One‐bit full adder and subtractor circuits are designed using SFV‐QCA gate and compared with the previous works. The analysis of the SFV‐QCA gate shows that it is ultraefficient and more robust as compared to previous works. Energy dissipation analysis of the designs has also been presented, and the investigation establishes minimum energy dissipation of the designs that confirms ultrahigh efficient designs.
