Abstract
An integrated inductive element may be formed over a substrate. A triple well may be defined in a star-shape, in one embodiment, in the substrate beneath the integrated inductive element in order to reduce eddy current losses arising from magnetic coupling between integrated inductors associated with the same integrated circuit.
