CIRCUIT FOR SIGNAL READING FROM PHOTOSENSOR ARRAY CELLS Russian patent published in 2009 - IPC H01L27/148 H04N5/335 

FIELD: electronics.

SUBSTANCE: circuit for signal reading from photosensor array cells that contains located in cell transistor switch for potential recovery in integrating condenser, source-follower amplifier connected by its drain to constant potential bus, by its source - via addressing transistor to signal bus loaded out of cells to current generator which is included, together with connected addressing transistor, signal bus, constant potential bus and current generator, in differential amplifier circuit. In this circuit source-follower amplifier connected by its constant potential bus to current mirror input forms input portion of amplifier with positive input, and input portion with negative input is formed by transistor connected by its source with current generator, by its drain - with current mirror output - amplifier output and with gate thus creating unity negative feedback.

EFFECT: creation of new signal reading circuit.
