Abstract:
The present invention in a single structure combines a pad comprising a connection terminal suitable for connecting the circuit elements integrated in a chip to circuits outside of the chip itself and at least one condenser. By combining a connection pad and a condenser in a single structure it is possible to reduce the overall area of the chip that otherwise in common integrated circuits would be greater due to the presence of the condenser itself. In this way, the costs and size of the chip can be reduced.
