Floating diffusion node
WebNov 7, 2007 · The floating diffusion node 60 voltage would thereby be boosted to about 3.3V (3.3V=4V−0.7V=2.8V+0.5V). Accordingly, the floating diffusion node 60 is reset in a manner providing it with a greater full well capacity than is possible using Vaa as the reset voltage (charge of the floating diffusion node 60=C×V). In addition, problems ... Webcapacitance ofthe floating diffusion node, tr and r~ arc as shown in Fig. 1(b) and ~c~ is the cutoff frequency of the in-pixel source-follower.
