Abstract

In recent years Quantum Cellular Automata (QCA) technology has emerged as an ideal option to substitute the current CMOS technology. QCA offers operation in the terahertz range, small area, and low power in nano-scale circuit design. This paper explores the application of quantum dot cellular automata(QCA) technology in efficient floorplanning of digital code converters using the tile based architecture of QCA XOR gate. The proposed code converter circuits exhibits the benefits of low cell count, area, cost and low energy dissipation. The suggested layouts have achieved the 11.42% reduction in cell count, 29.53% reduction in total occupational area,30.93% reduction in cost and 11.52% increase in area utilization factor in comparison to similar counterparts. The functional validity of the suggested designs were validated using QCADesigner 2.0.3 tool. In addition, the energy dissipation analysis were calculated using the QCAPro tool at standard tunelling energy levels o 0.5E_K, 1.0E_K, 1.5E_K.

基于量子点元胞自动机的高效纳米码转换器建模

近年来，量子元胞自动机（QCA）技术已成为替代现有CMOS技术的理想选择。QCA提供太赫兹范围内的操作，小面积，低功耗的纳米级电路设计。本文探讨了量子点元胞自动机（QCA）技术在基于量子点元胞自动机异或门结构的数字码转换器的高效布局中的应用。所提出的编码转换电路具有低单元数、低面积、低成本和低能耗的优点。与同类布局相比，建议布局的单元数减少11.42%，总占地面积减少29.53%，成本降低30.93%，面积利用率提高11.52%。采用qcaddesigner 2.0.3工具对建议设计的功能效度进行验证。此外，使用QCAPro工具计算了0.5EK、1.0EK、1.5EK标准隧道能量水平下的能量耗散分析。
