基于双流体理论的超导过渡区边缘传感器器件建模
Device modeling of superconductor transition edge sensors based on the two-fluid theory
摘要：
为了支持复杂的大规模过渡边缘传感器（TES）电路的设计和研究，我们使用基本的SPICE元素开发基于超流-正常流体理论的TES的器件模型。与以前的研究相比，我们的器件模型不限于小信号模拟，它只依赖于器件参数，有明确的物理意义，可以很容易地测量。我们将器件模型集成在基于强大的EDA工具（如CADENCE和OrCAD）的设计工具包中，并将其用于TES电路的多功能仿真。比较我们的模拟结果与发表的实验数据，我们发现很好的协议，这表明基于双流体理论的设备模型可以用来预测TES电路的行为可靠，因此，他们是有价值的辅助复杂的TES电路的设计。
英文摘要：
In order to support the design and study of sophisticated large scale transition edge sensor (TES) circuits, we use basic SPICE elements to develop device models for TESs based on the superfluid-normal fluid theory. In contrast to previous studies, our device model is not limited to small signal simulation, and it relies only on device parameters that have clear physical meaning and can be easily measured. We integrate the device models in design kits based on powerful EDA tools such as CADENCE and OrCAD, and use them for versatile simulations of TES circuits. Comparing our simulation results with published experimental data, we find good agreement which suggests that device models based on the two-fluid theory can be used to predict the behavior of TES circuits reliably and hence they are valuable for assisting the design of sophisticated TES circuits.
