Complementary metal-oxide semiconductor (CMOS) image sensor

摘要

A CMOS image sensor includes a unit pixel including controlled by a high voltage; a reference high voltage generator for generating a reference high voltage; and a high voltage output unit for generating the high voltage by using the reference high voltage as an operating voltage to thereby output the high voltage to the unit pixel, wherein a level of the high voltage is stably maintained regardless of a variations of the reference high voltage level.
