CMOS图像传感器的研究与设计-微电子学与固体电子学专业毕论文.docx

Abstract III Abstract CMOS image sensor is all important embranchment of the solid state Image sensor． 、阢也the development of semiconductor technology,photoelectron technology,internet technology and multimedia technology,CMOS image sensor technology has been paid much attention to and developed quickly．CMOS image SenSOr is applied widely in the fields of science research，industry production，medical treatment and communication． The chip of CMOS image SenSOr is integrated by pixel sensor array,analog circuit， and di西tal circuit．It is VLSl with full function．Comparing而t11 the CCD image SenSOr technology,CMOS image SenSOr has many advantages such as low cost，low power, high integration．It has the foreground of wide application．So research and develop CMOS image SCUsor has very important meaning． In this thesis the history of the solid state Image sensor is introduced，CMOS image sensor is compared with the CCD．The photoemission，action principle of CMOS image sensor,performance character,pixel configuration is researched；The model of pixel action is set，The expression of dynamic range and Signal Noise Ratio is worked out．At last a 4T2S—APS pixel layout was design basing on HeJian 0．1 Sum process．The design of pixel is a part of CMOS image sensor system on chip．The whole chip Was fabricated in May 2007 by means of MPW．The result of test is all right，the quality of image is nice． Keywords：CMOS Image Sensor Dynamic Range Share Configuration Pixel  西安电子科技大学 学位论文独创性(或创新性)声明 秉承学校严谨的学风和优良的科学道德，本人声明所呈交的论文是 我个人在导师指导下进行的研究工作及取得的研究成果。尽我所知，除 了文中特别加以标注和致谢中所罗列的内容以外，论文中不包含其他人 已经发表或撰写过的研究成果；也不包含为获得西安电子科技大学或其 它教育机构的学位或证书而使用过的材料。与我一同工作的同志对本研 究所做的任何贡献均已在论文中做了明确的说明并表示了谢意。 申请学位论文与资料若有不实之处，本人承担一切的法律责任。 本人签名： 裂缝趔 日期丝幽垄旦 西安电子科技大学 关于论文使用授权的说明 本人完全了解西安电子科技大学有关保留和使用学位论文的规定， 即：研究生在校攻读学位期间论文工作的知识产权单位属西安电子科技 大学。学校有权保留送交论文的复印件，允许查阅和借阅论文；学校可 以公布论文的全部或部分内容，可以允许采用影印、缩印或其它复制手 段保存论文。同时本人保证，毕业后结合学位论文研究课题再攥写的文 章一律署名单位为西安电子科技大学。 (必威体育官网网址的论文在解密后遵守此规定) 本学位论文属于必威体育官网网址，在——年解密后适用本授权书。 本人签名：塾黎逖导师签名：弋旁妒． 日期垄仝聋』笪堑鱼日期—乃夏产何
