An addition in digital signal processing is an
important constructional unit for making all arithmetic operations. A full
adder is a simple circuit that adds binary numbers. Ripple carry adder (RCA) is
a cascade of the full adders that is used to add 8, 16, 32, etc. bit numbers.
In this paper, multi-bit RCA is designed based on promising nanotechnology
Quantum-dot Cellular Automata (QCA). In fact, QCA is getting investigated as an
alternative to currently silicon-transistor based technology. The proposed RCA
adder is designed as multilayer structure and is found as low complexity design
in comparison with other RCA designs.
