摘要

本論文是有關低瞬態互調失真功率放大器與降壓型直流對直流轉換器的實做以及測試方法做以研習與探討。低瞬態互調失真功率放大器是利用放大器之回授技巧，控制電晶體工作點，來增加功率放大器之線性度，使之能處理快速的瞬態訊號，而不會造成失真、削波等現象。本論文整理出詳細的設計流程，SPICE模擬方式，以及測試要點與結果。在直流對直流轉換器驗證驗證方法中，本論文整理出一般業界最常使用之驗證方法，並加以分析及說明，以及從設計者的觀點，來說明如何驗證與設計一個能符合各項電氣規格的直流對直流轉換器。

In this thesis, we studied the implementation and verification methodologies for low TIM power amplifier & bulk DC/DC regulator. For low TIM power amplifiers, multi-path feedback method and the transistor operation point controls are employed to increase the linearity such that the amplifier can process a fast transient signal without distortion and clipping. In the first part of the thesis, we survey the detail design procedures, SPICE simulation settings, test requirements, and the results for the low TIM power amplifier. As the second part, the verification methodologies for bulk DC/DC regulator were surveyed. We illustrated the most universal verification methods in the industry and explained the methods of design which can make the DC/DC converters meet the electrical specifications.
