Abstract:
A pixel circuit comprising: a light-sensing element; a first transistor having its control node coupled to a sense node and its source coupled to a readout path of the pixel circuit; and a reset voltage correction circuit comprising: a first switch configured to selectively couple an input node of the reset voltage correction circuit to a correction node, the input node being connected to the sense node or to the source of the first transistor, the correction node being coupled by a capacitance to the sense node; and a second switch configured to selectively couple the correction node to a reset voltage.
