Abstract
The quantum-dot cellular automata (QCA) is a novel technology with greater potential to provide circuits with small size and high speed compared with complementary metal–oxide–semiconductor (CMOS) technology. This paper presents and evaluates a novel serial–parallel QCA multiplier circuit based on a designed efficient full-adder circuit. The designed circuits are simulated using QCADesigner version 2.0.3. The results demonstrate that the proposed circuits have advantages in comparison with other QCA circuits in terms of cell count, area, and cost.
