Patent ID: 7202648

Claim:
A die comprising: an inductor comprising magnetic material selected from the group consisting of amorphous CoZrTa, CoFeHfO, CoAlO, FeSiO, CoFeAlO, CoNbTa, CoZr, and other amorphous cobalt alloys; a switch to energize the inductor; and a switch controller to switch the switch ON and OFF at a frequency and with a duty cycle, wherein the frequency is greater than 100 MHz, wherein the inductor further comprises a first sub-structure comprising a first conductor, the first conductor comprising upper portions and lower portions; and a second sub-structure in electrical contact with the first conductor and comprising a second conductor, the second conductor comprising upper portions and lower portions; wherein a magnetic flux due to a DC current flow in the inductor is such that the magnetic flux due to the DC current flow in the lower portions of the first conductor is aligned with the magnetic flux due to the DC current flow in the upper portions of the second conductor, and the magnetic flux due to the DC current flow in the upper portions of the first conductor is aligned with the magnetic flux due to the DC current flow in the lower portions of the second conductor.
