WebFeb 27, 2016 · During the transmission process, the lenses reduce the size of the projected visible light image and transfer the image to one or more small capacitors that convert the light into an electrical charge. This charge is stored in a sequential pattern and released line by line and sent to an analog-to-digital converter (ADC) ( Figure 6-1 ). The basis for the CCD is the metal–oxide–semiconductor (MOS) structure, with MOS capacitors being the basic building blocks of a CCD, and a depleted MOS structure used as the photodetector in early CCD devices. In the late 1960s, Willard Boyle and George E. Smith at Bell Labs were researching MOS technology while working on semiconductor bubble memory. They realize…
