Abstract
An imaging pixel (2) to mitigate cross-talk effects comprises a voltage supply node (VN) to receive a supply voltage (VDD), and an output node (ON) to provide a pixel output signal. The imaging pixel (2) further comprises a photosensitive element (10), and a source follower transistor (31) having a control node coupled to the photosensitive element (10). The source follower transistor (31) is interposed between the voltage supply node (VN) and the output node (ON). The imaging pixel (2) comprises a clamping circuit (20) being interposed between the voltage supply node (VN) and the output node (ON).
