Small Pixels for Novel CMOS Image Sensors

Abstract

This paper presents recent results of small pixel development for different applications and discusses optical and electrical characteristics of small pixels along with their respective images. The paper provides a comparison of front side illumination (FSI) with back side illumination (BSI) technology and considers tradeoffs and applicability of each technology for different pixel sizes. Additional functionalities that can be added to pixel arrays with small pixel, in particular high dynamic range capabilities, are also discussed.
