Abstract

This thesis provides a thorough analysis of the linearity characteristics of a CMOS image sensor. Firstly, this thesis analyzes the factors that cause the nonlinearity of the image sensors. These factors are then verified by simulation results of a proposed behavioral model and the measurements in a prototype chip. Secondly, different techniques are presented to improve the linearity of the whole imaging system; and the effectiveness of these techniques is further confirmed by measurement results of several test chips.
