Synthesis Methods of Baugh-Wooley Multiplier and Non-restoring Divider to Enhance Primitive’s Results of QCA Circuits

As a semiconductor industry continues growing toward miniaturization and high speed, it is challenged by the rising uncertainties in the scaling for further devices shrink in the nanometer scale. Scaling leads to quantum effect at the nanoscale. Quantum dot cellular automata (QCA) is the alternative approach to synthesize the digital logic circuits with high density and high computation speed. In this paper, an accurate approach to synthesize and optimize the Baugh-Wooley multiplier and non-restoring divider in the presence of QCA technology has been proposed. The proposed designs are robust and utilize a wire-crossing type of single layer, with minimal clock phasing. The synthesis approach and optimization are perfectly scalable across layout construction of designs and can find better primitive’s results of QCA circuit performance.
