Design a lightweight low power multiplier circuits using quantum dot cellular automata architecture

In this paper, we propose a powerful multiplier circuit using QCA 3-dot cell. The architecture is very competent to calculate the multiplication between two numbers. Here, we use a 4-bit 3-dot QCA adder to construct our proposed circuit, which has less number of cells and area from other QCA based adders. [1,2,3] Our new and novel design is improved a lot from existing multipliers, the suggested multiplier circuit enhances 28% on cell, 99% on area than the current finest known one.
