Quantum dot cellular automata (QCA)-based demultiplexer or DeMUX is a basic module of nanocommunication and nanocomputation, like a multiplexer. However, the design and analysis of demultiplexer using QCA have been neglected by researchers, unlike multiplexer. This article proposed and analyzed a simple and optimized QCA-based single-layered demultiplexer only using two majority gates, one inverter and two clocks. Our proposed area-efficient DeMUX has a complexity of 21 QCA cells, which covered a total area of 20,412 nm 2 and a cell area of 6804 nm 2 with area usage of 33.33%. The latency of the proposed block is 0.5 clock, and the calculated cost is 20. The energy dissipation analysis using QDE tool shows that the total energy dissipation is 8.64e−003 eV and the average energy dissipation per cycle is 7.85e−004 eV of QCA demultiplexer. Also, energy has been calculated using the popular tool QCAPro in three tunneling levels with $$\gamma =0.5E_{\mathrm{K}},\gamma =1.0E_{\mathrm{K}}$$ γ = 0.5 E K , γ = 1.0 E K and $$\gamma =1.5E_{\mathrm{K}}$$ γ = 1.5 E K at 2K temperature, and the total energy dissipated as 32.86 meV, 41.41 meV and 52.21 meV, respectively.

使用量子点元胞自动机的最优解复用器单元设计和能量估计

基于量子点元胞自动机 (QCA) 的解复用器或 DeMUX 是纳米通信和纳米计算的基本模块，类似于多路复用器。然而，与复用器不同，使用 QCA 的解复用器的设计和分析一直被研究人员忽视。本文提出并分析了一种简单且优化的基于 QCA 的单层解复用器，仅使用两个多数门、一个反相器和两个时钟。我们提出的面积高效的 DeMUX 具有 21 个 QCA 单元的复杂性，覆盖了 20,412 nm 2 的总面积和 6804 nm 2 的单元面积，面积使用率为 33.33%。提出的块的延迟为 0.5 个时钟，计算成本为 20。使用 QDE 工具的能量耗散分析表明，总能量耗散为 8.64e-003 eV，每个周期的平均能量耗散为 7.85e-004 eV。 QCA 解复用器。还，
