An integrated circuit transformer includes multiple metal layers in the structure of an integrated circuit in which are formed a first spiral inductor and a second spiral inductor. The first spiral inductor is aligned with and beneath the second spiral inductor such that the first spiral inductor acts to magnetically excite the second spiral inductor, while shielding it from resistance losses to the substrate.
