The half bridge backlight inverter is used to drive a CCFL. The control IC of the backlight inverter comprises a start-up circuit, an oscillator, an output stage circuit, a protecting circuit, a control circuit and a logic circuit. The thesis analyzes the high voltage part of the control IC and solves the drawback of the start-up circuit. The start-up circuit and the output stage is designed and simulated. The chip layout is also performed .The start-up circuit and the output stage circuit of the control IC is implemented by maximum gate to source 20V fabricating process. For power supply application with output voltage less than 30V. The power transistor integrated into the control chip could reduce area of whole system.第一章　序論…………………………………………………………１ １－１　研究背景與動機………………………………………１ １－２　論文架構………………………………………………３ 第二章　功率電晶體與高壓電路簡介………………………………５ ２－１　功率電晶體……………………………………………５ ２－２　背光逆變器控制晶片中的高壓電路………………２０ ２－３　背光逆變器控制晶片輸出功率電晶體保護電路…２７ ２－４　結論…………………………………………………３１ 第三章　高壓啟動電路……………………………………………３２ ３－１　啟動電路區塊………………………………………３２ ３－２　啟動電路之分析、設計與模擬……………………３５ ３－３　啟動電路佈局………………………………………４７ ３－４　結論…………………………………………………４８ 第四章　高壓輸出驅動級…………………………………………４９ ４－１　輸出級電路區塊……………………………………４９ ４－２　輸出級之分析、設計與模擬………………………５１ ４－３ 輸出級佈局…………………………………………６２ ４－４　結論…………………………………………………６３ 第五章　結論與展望………………………………………………６４ ５－１　結論…………………………………………………６４ ５－２　未來展望……………………………………………６５en-US背光逆變器高壓啟動電路驅動輸出級Backlight InverterUVLOOutput driverthesis
