Abstract
An output of a voltage regulator is a core voltage line that runs adjacent to a die attach area on a packaging substrate. An input of the voltage regulator is typically coupled to a power supply which, in one embodiment, is also an I/O voltage line that runs adjacent to the die attach area. In one embodiment, the core voltage line is shaped as a ring encircling the die attach area on the packaging substrate. In another embodiment, the I/O voltage line is also shaped as a ring encircling the die attach area on the packaging substrate. Further, a semiconductor die having at least one I/O Vdd bond pad and at least one core Vdd bond pad can be mounted in the die attach area. The I/O Vdd bond pad and the core Vdd bond pad can be connected, respectively, to the I/O voltage ring and the core voltage ring.
