An ultra-low noise photoconductive film image sensor with a high-speed column feedback amplifier noise canceller

We developed an ultra-low noise image sensor in which an organic photoconductive film (OPF) is laminated on the entire surface of the pixel circuits. In order to suppress the kTC noise in the pixel circuit of a three transistor configuration, a high-speed column feedback noise cancel circuit is newly developed. An ultra-low noise of 2.9 electrons during the horizontal blanking period of only 5 μs has been achieved.
