本文提出了一种快速积分方程法，用于提取RF IC、RF MEMS、IC封装和深亚微米IC等中的电感。该方法将最近发展的多级绿色函数插值法（MLGSTF）（1，2）与采用体积环（VL）基函数离散的体积积分方程相结合。在该模型中，我们使用传统的SWG基函数来模拟电感中的电流，而不是使用细丝模型来模拟电感中的电流，因为这种基函数对于复杂几何形状的问题是灵活的。最短路径算法也被用来找到源循环基函数。通过对直线电感、螺旋电感、凸点电感和并联母线电感的提取，验证了该方法的有效性。
In this paper,a fast integral equation method is developed for extracting the inductances in RF ICs,RF MEMs,IC packages,and deep submicron ICs etc. This method combines a recently developed Multilevel Green's Function Interpolation Method (MLGFIM) (1,2) with the volume integral equation discretized using Volume Loop (VL) basis functions. In it,instead of using the filaments model to simulate the currents flowing in the inductors,we use the conventional SWG basis functions for this kind of basis functions is flexible for problems with complex geometries. The shortest path finding algorithm is also used to find the source loop basis functions. The inductance extractions from the straight line,the spiral inductors,the bump,and the parallel buses in this paper demonstrate the validity and efficiency of this hybrid method.
