The structure of the driver is composed of ring oscillator, nonoverlapping clock generator, charge pump and level shifter, and it uses low dropout regulator (LDO) to reduce noise from the voltage source.irst, some charge pump circuits are reviewed. After comparing strengths and weaknesses of the circuits, a suitable charge pump is chosen to design high-voltage pulse driver. Second, a new charge pump is designed for converting DC into high-voltage pulse. In addition, this charge pump is designed to re-develop a new high-voltage pulse driver. These two newly designed drivers have their own strengths and weaknesses in different applications. Then, these structures are modified taking the drivers’ influence on LDO into consideration. Finally, the circuit is simulated by HSPICE, the layout is designed, and the chip is tested.第一章 緒論........................................................1 1.1 研究背景與動機................................................1 1.2 血液幫浦驅動電路模型.........................................3 1.3 論文架構.....................................................4二章 高壓脈波驅動電路設計........................................5.1 電荷幫浦.....................................................5 2.1.1 Dickson電荷幫浦..........................................5 2.1.2 動態CTS’s電荷幫浦.......................................9 2.1.3 雙迴路電荷幫浦..........................................12.2 間接式高壓脈波驅動電路設計..................................16.3 直接式高壓脈波驅動電路設計..................................22.4 時脈產生與驅動能力分工......................................31三章 高壓脈波驅動電路模擬.......................................33 3.1 間接式高壓脈波驅動電路模擬..................................333.2 直接式高壓脈波驅動電路模擬..................................383.3 低壓降穩壓器之輸出變化......................................40四章 實際電路量測...............................................41.1 間接式高壓脈波驅動電路晶片量測與分析........................41.2 直接式高壓脈波驅動電路晶片量測與分析........................46.3 直接式高壓脈波驅動電路驅動能力改良...........................51五章 結論.......................................................535.1 總結........................................................535.2 未來展望....................................................53考文獻............................................................541657226 bytesapplication/pdfen-US電荷幫浦高壓脈波驅動電路charge pumphigh-voltage pulsedriverthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/189045/1/ntu-97-R95943041-1.pdf
