在本論文中，我們開發了一個AB類運算放大器的自動化合成軟體，AB類運算放大器由於擁有良好的能量消耗效率及線性度，所以被廣泛地使用在許多類比電路中。然而即使是經驗豐富的電路設計者，設計一個AB類運算放大器並對其最佳化經常是一件耗時的工作。而對於系統設計者而言，也很難快速地在各個不同的製程條件下評估一個AB類運算放大器規格的可行性。在本論文中，我們基於人工設計所歸納出的經驗，針對AB類運算放大器歸納出系統化的設計流程，再根據這套設計流程，實現了一個制定元件尺寸的軟體工具。實驗結果顯示，本論文所開發之軟體所合成的AB類運算放大器，其效能與業界規格相比具有相當優異的競爭力。

In this thesis, we develop an automatic synthesis tool for class AB operational amplifier. The class AB operational amplifier is widely used in analog circuits because of its good energy consumption efficiency and linearity. However, even for experienced circuit designers, designing and optimizing a class AB operational amplifier is a time-consuming task. For system designers, it is difficult to quickly evaluate the feasibility of a target specification under different process conditions for a class AB operational amplifier. In this thesis, we develop a systematic design flow for class AB operational amplifier based on the designers’ experience and knowledge. Accordingly, a synthesis tool for device sizing has been developed. Experimental results show that the synthesized class AB operational amplifier can achieve competitive performance with industry products.
