This thesis provides a thorough noise analysis for conventional CIS readout chains, while also presenting and discussing a variety of noise reduction techniques that allow the read noise in standard processes to be optimized. Two physical implementations featuring sub-0.5-electron RMS are subsequently ...
Reset noise reduction through column-level feedback reset in CMOS image sensors主要由李斌桥、徐江涛、谢爽编写,在2011年被《半导体学报》收录,原文总共5页。
sources. One of the sources of noise in CMOS image sensors is row-wise temporal noise. This noise shows up as strips that change their locations every time a new frame of an image is captured. The strips are not spatially fixed or stationary and their locations are a function of time, ...
