Abstract
An integrated circuit includes at least an inductive element and an active region which may include resistive, capacitive and semiconductor elements. The inductive element and part of the active region are superimposed. The integrated circuit has a screen for insulating the active region with respect to an electromagnetic field that the inductive element develops. The screen allows the implementation of inductive elements having high quality factors in integrated circuits of reduced size and in which the electromagnetic interactions between the inductive elements and the other elements are reduced.
