In order to save energy, an output driver circuit by the idea of regulable output voltage is presented. There are two different methods to do this. One is using the basic idea of level-shifter and modifying the basic structure. The other one is using the idea of linear regulator to regulate output voltage of an output driver. Both of the methods can satisfy the requirement of saving energy. However, the modified level-shifter costs larger area and additional reference circuit. As a result, a modified linear regulator was applied. Finally, the real IC test outcomes are verified.第一章 序論...............................................1 1.1 研究背景與動機........................................1 1.2 論文架構..............................................4 第二章 基本架構介紹.......................................5 2.1 位準平移器............................................5 2.2 基本的高壓輸出驅動級..................................8 第三章 可調整輸出的省電效果..............................10 3.1 改良動機.............................................10 3.2 可調整輸出的優點.....................................10 3.3 可調整輸出對系統端的影響.............................13 第四章 位準平移式可調輸出驅動級..........................14 4.1 可調輸出的位準平移器.................................14 4.2 工作步驟.............................................16 4.3 電路不理想的特性.....................................19 第五章 線性穩壓式可調整輸出..............................20 5.1 線性穩壓器...........................................20 5.2 電路架構.............................................23 5.3 工作步驟.............................................30 5.4 比較器的替代.........................................33 5.5 取樣電組的功率消耗...................................34 5.6 模擬結果.............................................35 第六章 佈局與IC量測......................................37 6.1 佈局與實際IC.........................................37 6.2 晶片的量測...........................................39 第七章 總結..............................................42 7.1 總結.................................................42 7.2 未來展望.............................................421382556 bytesapplication/pdfen-US輸出驅動級Output Driverthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/57382/1/ntu-96-R94943114-1.pdf
