As the name suggests, CMOS image sensors are fabricated in a standard CMOS technology. This is a major advantage because it allows us to integrate the sensor with other analog and digital circuits required for an imaging system. An integrated solution allows us to reduce the power consumption … See more Most CMOS photo-detectors are based on the operation of a PN-junction photodiode. When a photodiode is reverse-biased (and the reverse voltage is … See more The basic structure of a CMOS image sensor is depicted below. A two-dimensional array of photo-detectors is used to sense the incident light intensity. The charge created … See more A reverse-biased photodiode produces a current component that is proportional to the incident light intensity. A two-dimensional array of these photo-detectors can be used to … See more With many CMOS image sensors, the exposure cycle of different pixel rows start at slightly different times. Typically, the rows are reset in sequence from top to the bottom. After the … See more WebCMOS sensor. A CMOS sensor is an electronic chip that converts photons to electrons for digital processing. CMOS (complementary metal oxide semiconductor) sensors are used to create images in digital cameras, digital video cameras and digital CCTV cameras. CMOS can also be found in astronomical telescopes, scanners and barcode readers.
