摘要: 
近幾年來,隨著個人消費性電子產品、第三代行動通訊服務、照像手機與數位相機的蓬勃發展,非晶矽薄膜電晶體液晶顯示器得以大幅成長,但隨之而來的,面板成本下降壓力也愈來愈大,而在驅動IC上,也面臨著相同情況,加上面板廠的合併,更使得晶片毛利降的更是低。在本論文中探討了如何降低驅動IC的面積與靜態功率消耗以提升產品競爭力與毛利。而要達到這兩項目標,最重要的就是運算放大器的設計。而近年來,大多數的相關文獻也都是以此電路方塊進行整個驅動電路結構的改良。所以,在本論文中以0.35μm 3.3V CMOS製程製作了三顆晶片,首先設計了兩種運算放大器,一顆是適用於大尺寸面板或B類架構小尺寸面板的驅動IC,而另一顆則是適合用於C類架構的驅動IC或是由本論文所提出的一個新電路架構之D類驅動IC,可以達到驅動QCIF+(176RGB×240)解析度之小尺寸面板。最後以那可以運作於D類的運算放大器實際地去設計與實作一顆262K色的源極驅動晶片,以驗證該運算放大器的實際性能。而從該使用D類結構的驅動電路得到數據分析,在面積上將比傳統驅動電路減少了約54%,靜態功率消耗也只有約2.7%。

Recent few years, to follow the rapid development of the consuming portable、third generation of mobile-phone-services、camera phone and digital camera, the a-Si TFT-LCD can grow up quickly, but the cost down issue of TFT-LCD panel is also urgent. And the driver chip meets the same situation. Besides, the operating profits are lower and lower as panel factories are merged. In this thesis, we study the circuit architecture how to decrease the chip area and the quiescent current to increase the competitive advantages and profits of the product. To achieve above two goals, the most important design is the OPAMP, and many researches also use this circuit block to improve the panel driver chip in recent years. Thus, we realize three chips by 0.35μm 3.3V CMOS process in this thesis. At the first, we design two kinds of OPAMP. OPAMP1 is used in large panel or small panel of B type architecture, and the other, OPAMP2 is suitable for C type or D type driver which presented in this research. Final, we use the OPAMP2 to realize one 262K-colors TFT-LCD source driver which can drive one QCIF+(176RGB×240) resolution panel to verify the performance of the OPAMP2. According to the measuring and simulating results of the type D source driver, it reduces about 54% chip area, and wastes around 2.7% quiescent current comparing to conventional source drivers.
