Abstract
An inductive structure having at least one winding or at least one coil and developed around a ferromagnetic core. Advantageously, the ferromagnetic core is formed by means of a multilayer ferromagnetic structure and the inductive structure is integrated in an electronic device. An inductor, a transformer, a sensor and a relay can be formed by means of the inductive structure proposed, as well as a method for integrating it in a package of an electronic device.
