WebNov 7, 2007 · The four transistor pixel 10 also typically has a floating diffusion node 60, connected to the gate of the source-follower transistor 30. Charge accumulated by the photo-conversion device 20 is first stored in the photo-conversion device 20 during an integration period and later transferred to a storage region, i.e., floating diffusion node 60 . WebA dual-capture wide dynamic range CMOS image sensor using an in-pixel floating-diffusion (FD) storage capacitor is proposed. The proposed structure uses the FD as a storage capacitor.

WebA method, apparatus and system are described providing a high dynamic range pixel. An integration period has multiple sub-integration periods during which charges are accumulated in a photosensor and repeatedly transferred to a storage node, where the charges are accumulated for later transfer to another storage node for output.
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.
