Design of a low-delay 4-bit parallel prefix adder using QCA technology
Abstract This paper presents a novel low-delay 4-bit Parallel Prefix Adder (PPA) implemented as a multilayer circuit using Quantum Dot Cellular Automata (QCA) technology. PPAs are among the most suitable architectures for high-speed digital design, offering significant advantages in scalability and...
