  • Abstract
    A combined linear and logarithmic image sensor is implemented in a 0.35 μm 1P3M technology. The pixel is 7.5×7.5 μm2 with a 37% fill factor and contains only 4 transistors. Offset calibration in the logarithmic region is realized by using electrical charge injection into the photodiode. The sensor achieves 120 dB DR and the offset calibration reduces the FPN from 13 mV to 5 mV.
