Abstract
This paper is proposed a 8-bit analog to digital converter for CMOS image sensor. A analog to digital converter for CMOS image sensor is required function to control gain. Frequency divider is used In control gain in this proposed analog to digital converter. At 3.3 Volt power supply, total static power dissipation is 8㎽ and programmable gain control range is 30㏈. Newly suggested analog to digital converter is designed by 0.35um 2-poly 4-metal CMOS technology.
