Device parameter variation to optimize performance is a very crucial step in the development of a technology. In this work we vary the maximum kink energy of a QCA circuit to perform an error-power tradeoff study in QCA design. We make use of graphical probabilistic models to estimate polarization errors and non-adiabatic energy dissipated in a clocked QCA circuit and demonstrate the tradeoff studies on the basic QCA circuits such as majority gate and inverter. We also show how this study can be used by comparing two single bit adder designs. The study will be of great use to designers and fabrication scientists to choose the most optimum size and spacing of QCA cells to fabricate QCA logic designs.}, keywords={cellular automata, logic design, quantum computing, quantum dots, quantum well devicesQCA circuit design, QCA logic design, clocked QCA circuit, error-power tradeoffs, graphical probabilistic model, maximum kink energy, nonadiabatic energy dissipation, polarization errors, quantum-dot cellular automata}, doi={10.1109/NANO.2008.158}, ISSN={}, }
