CMOS is a type of integrated circuit chip manufacturing process that can be used for many things, including digital camera image sensors.hey also require less power to use than do CCD sensors, which makes them popular in mobile devices. The drawback to CMOS sensors when used in cameras is that they tend to create photographs with a lot of image noise when used in lower light situations, though this is not always the case.
CMOS. Stands for Complementary Metal Oxide Semiconductor.. This technology is typically used in making transistors. The complementary part of the term unfortunately does not mean these semiconductors are free.Instead, it refers to how they produce either a positive or negative charge.ecause CMOS-based transistors only use one charge at a time, they run efficiently, using up very little power. This is because the charges can stay in one state for a long period of time, allowing the transistor to use little or no power except when needed.
