Abstract
The invention concerns an image sensor comprising: at least one pixel having a photodiode (PD); a sensing node (SN) coupled to the photodiode via a transfer gate (); and a further node (AN) coupled to the sensing node (SN) via a first transistor (); and a control circuit () adapted: to apply, during a reset operation of the voltage levels at the sensing node (SN) and further node (AN), a first voltage level (VDD) to a control node of the first transistor (); and to apply, during a transfer operation of charge from the photodiode (PD) to the sensing node (SN), a second voltage level (VSK) to the control node of the first transistor (), the second voltage level being lower than the first voltage level and higher than a ground voltage of the pixel.
