Abstract
According to some embodiments, an integrated circuit device is disclosed. The integrated circuit device include at least one inductor having at least one turn, a magnetic coupling ring positioned adjacent to the at least one inductor, the magnetic coupling ring comprising at least two magnetic coupling turns, the at least two magnetic coupling turns are disposed adjacent to the at least one turn to enable magnetic coupling between the at least two magnetic coupling turns and the at least one turn The integrated circuit device also includes a power electrode and a ground electrode, wherein the power electrode and the ground electrode are coupled to the at least one inductor and the magnetic coupling ring to provide a first current in the at least one inductor having a direction opposite to a second current in the magnetic coupling ring to cancel at least a portion of a magnetic field generated by the at least one inductor.
