Abstract :
This paper explores the design of parallel multipliers for Quantum-Dot Cellular Automata. Array multipliers, Wallace multipliers, Dadda multipliers, and quasi-modular multipliers are designed and analyzed. Quasi-modular multipliers use 4 (n/2 × n/2) modules to make n × n multipliers are also considered. All of these designs are constructed using coplanar layouts. The delay, area and complexity are compared for several different operand sizes using the QCADesigner simulator.
