Characterization of the Buried Channel n-MOST Source Followers in CMOS Image Sensors
نویسندگان
چکیده
The performance of CMOS image sensors in a deep sub-micron CMOS process is limited by two factors: 1) The increasing pixel temporal noise floor dominated by the 1/f noise from the pixel source follower (SF) and 2) The decreasing pixel analog swing due to the supply voltage scaling. In this paper, we present the possibility of using a buried channel n-MOST as the in-pixel source follower to reduce noise and enhance the pixel analog swing.

Performance of buried channel n-type MOSFETs in 0.18-μm CMOS image sensor process
Buried channel (BC) MOSFETs are known to have better noise performance than surface channel (SC) MOSFETs when used as source followers in modern Charge Coupled Devices (CCD). CMOS image sensors find increasing range of applications and compete with CCDs in high performance imaging, however BC transistors are rarely used in CMOS. As a part of the development of charge storage using BC CCDs in CM...
