Design of a 4-bit ripple adder using Quantum-dot Cellular Automata (QCA)

Quantum-dot Cellular Automata (QCA) is one of the new emerging nanotechnologies explored as an alternative to current CMOS designs. This paper presents the fundamental concepts of QCA and QCA-based logic design. Basic QCA logic circuits such as the inverter, three-input majority gate and five-input...
