Floating diffusion gate
WebDec 1, 2024 · I'm learning about the workings of image sensors and one area that I got stuck on is the use of a Floating Diffusion (FD) node in a pixel. From what I understand, it acts as a capacitor that collects the electrons from the photodiode during readout. 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.
