A new active pixel structure with a pinned photodiode for wide dynamic range image sensors
نویسندگان
چکیده
A wide dynamic range CMOS image sensor based on a new active pixel structure with a pinned photodiode is proposed and evaluated with device simulations. The proposed pixel device has a linear and a logarithmic characteristics in low and high illumination region, respectively. The technique of direct detection of photodiode potential leads to a wide logarithmic response compared with the conventional linear-log wide DR image sensor with pinned photo diode.

CMOS image sensors have become very popular in low cost imaging devices. In order to realize images of high quality, the image sensors need to have a high resolution, be able to achieve a high Signal-to-Noise ratio (SNR) and have a wide dynamic range. To increase the spatial resolution of the image sensors, the pixel size has been scaling down allowing integration of more pixels in a given die ...
