閘極液晶顯示器驅動電路:絕熱電路應用

Abstract

本論文提出ㄧ使用了互補式 絕熱/提升電容技術之有效率耗能的金氧半大負載驅動電路，並將之應用於薄膜電晶體液晶顯示器閘極驅動電路中。 第一章中將說明低電壓電路設計的趨勢和在低電壓操作下其優缺點。 第二章說明絕熱電路之原理，分析數個傳統多時脈，單一時脈絕熱電路家族和一般提升式驅動電路並說明其優劣。 第三章提出一個使用了互補式 絕熱/提升電容技術之有效率耗能的金氧半大負載驅動電路。經過HSPICE模擬後，與傳統的邏輯和驅動電路作效能比較，証明此電路在速度、功率回收與訊號的完整度上較原電路具有更好的表現。 第四章介紹薄膜電晶體液晶顯示器驅動電路原理並將第三章所提出之電路應用其中，並考量其電路佈局。

This thesis reports a new Energy-Efficient CMOS Large-Load Driver Circuit with the Complementary Adiabatic/Bootstrap (CAB) and use it in TFT-LCD gate driver circuit In chapter 1, the trend of low voltage design, and its good and bad in recent years will be described In chapter 2, the principles of adiabatic technology will be described. Then several conventional adiabatic and bootstrapped driver circuit families are reviewed, and analyzed with discussion about the advantages and disadvantages. In chapter 3, new Energy-Efficient CMOS Large-Load Driver Circuit with the Complementary Adiabatic/Bootstrap (CAB) Technique are proposed. And by HSPICE simulation, it is proved that in speed ,power Consumption, have been improved to compare with conventional single path circuits. In chapter 4, introduce operation principle of TFT-LCD gate driver circuit and use (CAB) circuit in TFT-LCD gate driver circuit .
