SYSTEMS FOR REDUCING MAGNETIC COUPLING IN INTEGRATED CIRCUITS (ICS), AND RELATED COMPONENTS AND METHODS

摘要

Systems for reducing magnetic coupling in integrated circuits (ICs) are disclosed. Related components and methods are also disclosed. The ICs have a plurality of inductors. Each inductor generates a magnetic flux that has a discernible axis. To reduce magnetic coupling between the inductors, the flux axes are designed so as to be non-parallel. In particular, by making the flux axes of the inductors non-parallel to one another, magnetic coupling between the inductors is reduced relative to the situation where the flux axes are parallel. This arrangement may be particularly well suited for use in diplexers having a low pass and a high pass filter.

1. A diplexer within a three dimensional (3D) integrated circuit (IC) (3DIC), comprising:
a first inductor having a first flux axis wherein the first inductor comprises a 3D inductor; and a second inductor having a second flux axis where the first flux axis and the second flux axis are not parallel.
