Claim 0:
1. 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, wherein capacitance coupling the correction node to the sense node is implemented at least partially by a capacitance present between the control node of the first transistor and a bulk of the first transistor.
