Abstract

A hybrid passive device for synergizing at least one passive component which resides in at least one technology is provided. The hybrid passive device includes a first passive component and a second passive component. The first passive component resides in a first technology of the at least one technology and/or a second technology of the at least one technology, the second technology is different from the first technology, and a technology boundary is arranged between the second technology and the first technology. The second passive component of the at least one passive component is different from the first passive component. The second passive component resides in the first technology and/or the second technology, and the first passive component and the second passive component are electromagnetically coupled to each other through the technology boundary.
