The table with parameters you translated is a picture, so the automatic translation engines ignore it. <br />40Ke full well and 60db DR numbers translate to 40e noise. I think that most of this noise is kTC - the result of 3T pixel architecture.<br />Generally, there are quite a few techniques to reduce kTC noise in 3T pixels. All of them assume that the photodiode is a well conducting plane. I'm not sure this assumption is correct in case of organic photodiode. It would be great if somebody can clarify this.Vladimir Koifmanhttps://www.blogger.com/profile/01800020176563544699noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-60216767213879820382009-10-06T04:41:15.695+02:002009-10-06T04:41:15.695+02:00Not a sensor professional here, but some more deta...Not a sensor professional here, but some more details, hope it helps<br /><br />Engineering sample specs<br /><br />Pixel pitch: 3.0um<br />Optical size: 1/15" (1.2mm diagonal)<br />Total array size: 360 x 256 pixels<br />Usable array size: 320 x 240 pixels<br />Frame Rate: 50 frames/sec<br />Full well capacity: 40000e<br />Dynamic Range: 60dB<br />Dark current: 7e at 60 degrees centigrade, 50fps<br />Quantum efficiency: 65% at 550nm<br />electron to voltage conversion: 56uV/e<br />Pixel fogging?: none<br />Image ghosting: cannot be detected using current apparatus<br />Organic Layers: - (unknown?, does not include AR film on pixel)<br />Pixel fill factor: 85%<br />metal layer Structure: 2 polysilicon layers, 4 "wire routing" layers<br />1 pixel uses 3 transistors<br />Process node: 180nm<br />Micro Lens: None<br /><br />Some more details of the article.

Their test sensor was 1/15" with a 3 micron pixel. The effective image 320*240 pixels. QE is 65%, and with antireflective film surpaces 80%. For a 550nm wave length<br />Fuji design is not sensitive to IR so doesn't need IR cut filter.<br />The main chalenge is stacking the three layers and the electrodes together. Fuji “needs to make the improvement to the nanometer stamping installment” .<br />Hope that someone more knowledgeable can help translating.<br />Image sensor world, thanks for the great blog.MuTakanoreply@blogger.com
