PHOTOELECTRIC CONVERTER CELL OF IMAGE RECEIVER Russian patent published in 2017 - IPC H01L31/101 H01L27/146 

FIELD: physics.

SUBSTANCE: photoelectric converter cell of the image receiver contains a photodiode, a charge transistor accumulated by the photodiode, a preset transistor providing restoration of the initial potential on the photodiode, an input transistor of the source follower, a row sampling transistor and a low-noise charge divider providing a small portion of the charge accumulated by the photodiode during relaxation, and its transmission to the gate of the input transistor of the source follower with multiple repetition of this procedure during the frame time.

EFFECT: increasing the signal-to-noise ratio and increasing the sensitivity of the cell.
