WebbThe imager is based on hybrid pixels whose photodiodes that can be configured to work as photosensors or tiny solar cells. The hybrid pixels allow the imager to harvest energy in between frames or while it is in sleep mode. As a proof of concept a 32x16 array of hybrid pixels has been designed and fabricated in a standard 0.5 um CMOS process. WebbA novel pixel structure, which is achieved by generating a non-uniform doped transfer transistor channel and shaping a PPD (Pinned Photodiode) like triangular tooth, has …
