Abstract. Quantum-dot cellular automata (QCA) is a potential upcoming nanotechnology for designing digital circuits with high performance. A subtractor is an important arithmetic circuit used in many digital circuits. An efficient multilayer full subtractor design is proposed using majority logic in QCA. The proposed design has only 53 cells and occupies a small area of about 0.03 μm2. Using the proposed subtractor, a 4-bit ripple borrow subtractor with 256 cells and an area of about 0.20 μm2 is realized. Verification and simulation are done using QCADesigner. Defect analysis is also done for the proposed subtractor. Energy dissipation of the proposed designs is done using QCADesignerE tool.

在量子点元胞自动机中使用多层交叉的高效多数逻辑减法器设计

摘要。量子点元胞自动机 (QCA) 是一种潜在的、即将到来的用于设计高性能数字电路的纳米技术。减法器是许多数字电路中使用的重要算术电路。在 QCA 中使用多数逻辑提出了一种有效的多层全减法器设计。提议的设计只有 53 个电池,占用的面积很小,约为 0.03 μm2。使用所提出的减法器,实现了具有 256 个单元和约 0.20 μm2 面积的 4 位纹波借用减法器。使用 QCADesigner 进行验证和模拟。还对建议的减法器进行了缺陷分析。所提议设计的能量耗散是使用 QCADesignerE 工具完成的。
