摘要:
This disclosure provides implementations of inductors, transformers, and related processes. In one aspect, a device includes a substrate having first and second surfaces. A first inducting arrangement includes a first set of vias, a second set of vias, a first set of traces arranged over the first surface connecting the first and second vias, and a second set of traces arranged over the second surface connecting the first and second vias. A second inducting arrangement is inductively-coupled and interleaved with the first inducting arrangement and includes a third set of vias, a fourth set of vias, a third set of traces arranged over the first surface connecting the third and fourth vias, and a fourth set of traces arranged over the second surface connecting the third and fourth vias. One or more sets of dielectric layers insulate portions of the traces from one another.
