Abstract :
A CMOS compatible photosensor with high output current levels, and an area-efficient scheme for automatic signal-range centring according to illumination conditions are presented. The high output current levels allow the use of these devices in continuous-time asynchronous imagers, as well as in high-sampling-frequency applications
