Floating diffusion gate
Pixel The standard CMOS APS pixel consists of a photodetector (pinned photodiode), a floating diffusion, and the so-called 4T cell consisting of four CMOS (complementary metal–oxide–semiconductor) transistors, including a transfer gate, reset gate, selection gate and source-follower readout transistor. … See more An active-pixel sensor (APS) is an image sensor, which was invented by Peter J.W. Noble in 1968, where each pixel sensor unit cell has a photodetector (typically a pinned photodiode) and one or more active transistors. … See more APS pixels solve the speed and scalability issues of the passive-pixel sensor. They generally consume less power than CCDs, have less image lag, and require less specialized manufacturing facilities. Unlike CCDs, APS sensors can combine the image sensor … See more • Angle-sensitive pixel • Back-illuminated sensor • Charge-coupled device • Planar Fourier capture array • Oversampled binary image sensor See more • CMOS camera as a sensor Tutorial showing how low cost CMOS camera can replace sensors in robotics applications • CMOS APS vs CCD CMOS Active Pixel Sensor Vs CCD. … See more Background While researching metal–oxide–semiconductor (MOS) technology, Willard Boyle and George E. Smith realized … See more Many different pixel designs have been proposed and fabricated. The standard pixel uses the fewest wires and the fewest, most tightly packed transistors possible for an active pixel. It is … See more • John L. Vampola (January 1993).
