Design of adder and subtractor circuits in majority logic‐based field‐coupled QCA nanocomputing
Carson Labrado, Himanshu Thapliyal · Electronics Letters · 2016
Quantum‐dot cellular automata (QCA) is an emerging field‐coupled nanotechnology that promises to outperform existing CMOS technology. Single‐layer QCA designs of full adder, full subtractor, ripple carry adder, and ripple borrow subtractor is proposed. The proposed designs are improved over both existing single‐layer designs and multilayer designs.
