Abstract
In described examples of a magnetically coupled structure on a substrate with an integrated circuit device, the structure includes a first coil in a differential configuration, a second coil located above the first coil in a generally stacked configuration, and a center tap connection to a winding of the second coil. The first coil includes a first differential terminal, a second differential terminal, and metal windings of the first coil. The first coil's metal windings form a continuous spiral electrical path between the first and second differential terminals. The first coil's metal windings include turns and crossing connections between the turns. The turns are fabricated in an integrated circuit metal wiring level, and the crossing connections are fabricated in at least one metal level other than the metal wiring level containing the turns. The center tap is positioned to create a balanced structure.
