Abstract:	隨著製程的不斷進步，單顆晶片中能容納的電晶體數量愈來愈多，也發展出將整個系統都整合進一顆晶片中的概念，但不同的電路區塊需要不同的電壓來供應，因此需要電壓轉換器來滿足此項需求。為了使電壓轉換器的設計能更加快速，本論文提出一套針對電壓控制模式切換式升壓轉換器的自動化設計流程，設計範圍包括轉換器電路及控制電路的元件參數，並考慮元件的寄生阻抗使設計結果能符合實際電路特性。為了實現整套流程，本論文已發展出一個自動化設計工具，讓使用者可以在工具的圖形介面中輸入所需的電路規格，接著工具會透過 C 語言程式進行穩態及小訊號分析來產生元件參數，並以 HSpice 進行模擬來驗證結果的正確性，而所有的步驟是以 Tcl/Tk 工具命令語言進行整合，也已成功地在 Linux 系統上測試完成。在所有的設計範例中，經由流程產生的電路皆可達到規格要求。With the improvement of manufacturing process, more and more transistors can be placed in a chip. It drives the demand to integrate the whole system into a single chip. However, different blocks may require different voltage supplies, which require power converters to generate those voltages. In order to accelerate the design of power converters, an automatic design flow for the voltage-controlled step-up switching converters is proposed. This flow includes the design of the converter circuit and control circuit. It also considers the parasitic resistance of each component to ensure that the design can confirm the results with real devices.To accomplish the flow, an automatic synthesis tool is implemented. Users can assign the specifications of the converter circuit on a simple graphical user interface (GUI). The steady state and small signal analysis are then auomatically executed to generate the parameter of each component by a C program. The result will be measured through HSpice simulation to confirm the circuit performance. All steps have been integrated with Tcl/Tk shell scripts and successfully tested on Linux platform. All the generated results meet the required specifications in the demonstrated cases.
