Efficient design of Baugh-Wooley multiplier in Quantum-Dot Cellular Automata

The design of digital circuits in Quantum Dot Cellular Automata (QCA) has been of active interest in the last decade. Prior work on signed multipliers that achieve low area as well as low latency is limited. This paper presents an efficient QCA design of the classical Baugh-Wooley multiplier. The design is based on a few new results in majority logic. Simulations in QCADesigner are also presented and they confirm the efficiency of the proposed design. © 2013 IEEE.
