Complementary metal-oxide semiconductor (CMOS) image sensors have attracted attention these days as these devices offer low power consumption and high sensitivity. Its application is not limited only up to digital cameras or mobile on-board cameras but it has tremendous achievements in UV spectroscopy, machine vision, IR vision etc. In this paper, CMOS Image Sensors are reviewed. The difference in charge coupled device (CCD) and CMOS image sensor (CIS) is illustrated on the basis of various performance parameters of an image sensor. A basic architecture of CIS along with the types of pixel structures viz. active, passive and diagonal pixel unit is described. This paper provides information about the latest on-chip Analog to Digital converters (ADCs) as well as the comparison among its types in order to come across the best ADC(s) that could be used to design an efficient imager unit.
