摘要

在RF被動電路設計的過程當中，電感的設計往往是最難處理和最耗時的一個環節。除了考慮電感值之外，電感當中的各種寄生效應以及電感所佔的面積都必須納入考量。
為了解決以上的問題，這篇論文提出了一套電感合成與最佳化的方法. 這套方法可以根據使用者的需求，找出一個最佳的電感結構。在這篇論文裡，我們描述了平面型螺旋電感的各項電氣特性，也基於此建構了一個電感等效電路，並利用部分元素等效電路(Partial element equivalent circuit)的原理，開發了一個可以快速地計算出電感的各種電氣特性的模擬計算引擎。有了這個模擬引擎之後，我們將它配搭上最佳化的軟體工具，成功地開發出一套可以自動合成與最佳化平面型螺旋電感的軟體工具。

In RF design, inductor design is often one of the most difficult and time consuming process. Aside from the desired inductance value, designers have to consider the quality factor, parasitic effects and also the total area.
In order to solve the problem mentioned on above, this thesis brings forward synthesis and optimization method which is capable to generate inductor’s physical parameters according to user’s specification. In this thesis, the electrical characteristics of an inductor and its loss mechanism are carefully analyzed. With the proper inductor equivalent circuit and partial element equivalent circuit (PEEC) method, we developed a simulation engine which is capable to predict the electrical characteristics of an inductor. The simulation engine is utilized and an optimization tool is developed based on the simulation engine.
By combining the simulation engine and optimization software, we developed a tool that can automatically synthesis the inductor layout and optimize its parameters according to designer’s requirement.
