    Abstract: A method and apparatus for multi-phase transformers (200) are described. In one embodiment, a coupled inductor topology for the multi-phase transformers comprising N primary inductors (210-240). In one embodiment, each primary inductor is coupled to one of N input nodes (201-1, 201-2, 201-3, 201-4) and a common output node (205). The transformer further includes N-1 secondary inductors (222-242) coupled in series between one input node (201-1) and the common output node (250). In one embodiment, the N-1 secondary inductors (222-242) are arranged to couple energy from N-1 of the primary inductors (220-240) to provide a common node voltage (250) as an average of N input node voltages (201-1, 201-2, 201-3, 201-4), wherein N is an integer greater than two. Other embodiments are described and claimed.

    Abstract: An inductor (1) for an integrated circuit or integrated circuit package comprises a three-dimensional structure. In one embodiment the inductor is arranged on an integrated circuit substrate in at least two rows (2, 3), each row comprising upper segments (32) and lower segments (34), with the upper segments being longer than the lower segments. The upper segments in a first row are offset 180 degrees from those in an adjoining row to provide greater coupling of magnetic flux. The materials and geometry are optimized to provide a low resistance inductor for use in high performance integrated circuits. In another embodiment the inductor is arranged on an integrated circuit package substrate. Also described are methods of fabricating the inductor on an integrated circuit or as part of an integrated circuit package.

    Abstract: A transformer integrated on a die, the transformer comprising a set of conductive lines (302) formed on the die within one layer and interconnected among each other so that no two lines belonging to any one winding are nearest neighbors. The set of conductive lines (302) is surrounded by a magnetic material (304), which may be amorphous CoZrTa, CoFeHfO, CoAlO, FeSiO, CoFeAlO, CoNbTa, CoZr, and other amorphous cobalt alloys. The transformer may be operated at frequencies higher than 10 MHz and as high as 1 GHz, with relatively low resistance and relatively high magnetic coupling between the windings.
