时域有限差分算法与遗传算法在平面螺旋电感设计中的应用
The Application of FDTD and Micro Genetic Algorithms to the Planar Spiral Inductors
文章通过电磁场时域有限差分(FDTD)算法与遗传算法(GA)相结合进行平面螺旋电感设计。通过优化单元网格大小，可优化设计整个平面螺旋电感（包含空气桥）的结构尺寸。介绍了该方法既能够进行严格的电磁场求解，又可以避免繁杂的实验过程，是优化设计的一种有效而准确的手段。
High Q inductors are the important elements for RF circuit design. In this paper, the FDTD method is applied to explain the crowding effect of the spiral inductor , which can never be accurately analyzed by analytical solutions. The experimental results verify the FDTD simulation. The micro genetic algorithms and FDTD are combined to design the high Q inductor. The results show the efficiency of this exploration.
