Abstract
An integrated circuit including a substrate, a conductive layer, at least one inductive element superposed on the conductive layer and formed by a metallic turn having an outer contour and an inner contour, which bound between them a surface referred to as the radiation surface, and insulating material for insulating the conductive layer from the inductive element. The conductive layer has a surface substantially identical to the radiation surface.
Claims20
An integrated circuit comprising:
- a substrate,
- a conductive layer arranged in connection with the substrate,
- at least one inductive element superposed on the conductive layer and formed by a metallic turn having an outermost contour and an innermost contour, which bound between them a surface referred to as a radiation surface, the turn of the at least one inductive element having a free space in a center defining an active zone which is not covered by the radiation surface, the active zone being receivable of capacitive, resistive or semiconductor elements, and
- means for insulating the conductive layer from the at least one inductive element,
- the conductive layer having a surface substantially identical to the radiation surface such that the conductive layer is situated around the active zone which is not covered by the radiation surface.
