ABSTRACT:
A power supply network (2) for an integrated circuit is provided, the power supply network (2) comprising a supply grid (4); a plurality of supply pads (6), each supply pad (6) being in electrical contact with an edge of the supply grid (4); a current spreader (8) for at least one of the plurality of supply pads (6), each current spreader (8) being in electrical contact with a respective supply pad (6) and the supply grid (4), each current spreader (8) being sized so that it overlaps with a respective portion of the supply grid (4); and each current spreader (8) having a lower electrical resistance than the supply grid (4). Further embodiments provide an integrated circuit with a power supply network as described above.
