What does CCD stand for ?
Answer: C
CCD stands for Charge-Coupled Device.
A CCD is an array of closely spaced MOS capacitors. Light falling on each pixel generates charge in proportion to its intensity, and by clocking the gate voltages in sequence the charge packets are passed from one capacitor to the next, like buckets in a line, until they reach an output amplifier that converts each packet to a voltage. Invented at Bell Labs in 1969, it was the image sensor in most digital cameras, scanners and telescopes before CMOS sensors took over.
The other expansions are invented. Control Circuit Design, Central Core Database and Composite Camera Device are not standard terms in electronics, and none describes the charge-transfer principle that gives the device its name.
