轻掺杂衬底内的电流传播用半椭圆来近似，以有效地估计衬底电阻。与现有工作相反，所提出的模型仅包含一个拟合参数。还开发了紧凑模型来确定几种常用结构（例如保护环和三井）的隔离效率。通过将模型与基于边界元法的商用基板提取工具进行比较，验证了这些模型的准确性。这些模型用于比较具有轻掺杂基板的工业混合信号电路中的几种隔离结构。
Current propagation within a lightly doped substrate is approximated with a half-ellipse to efficiently estimate substrate resistances. As opposed to existing work, the proposed model contains only one fitting parameter. Compact models are also developed to determine the isolation efficiency of several commonly used structures such as a guard ring and triple well. The accuracy of these models is verified by comparing the models with a commercial substrate extraction tool based on a boundary element method. These models are used to compare several isolation structures within an industrial mixed-signal circuit with a lightly doped substrate.
