Abstract: The present disclosure provides a vertical inductor structure in which the magnetic field is closed such that the magnetic field of the vertical inductor structure is cancelled in the design direction outside the vertical inductor structure, yielding a small, or substantially zero, coupling factor of the vertical inductor structure. In one embodiment, several vertical inductor structures of the present disclosure can be placed in close proximity to create small resonant circuits and filter chains.

Abstract: Radio frequency (RF) filters configured to filter undesired signal components (e.g., noise and harmonics) from RF signals are disclosed. In one embodiment, an RF filter includes a first inductor coil having a first winding and a second inductor coil having a second winding and a third winding. The second winding of the second inductor coil is configured to have a first mutual magnetic coupling with the first winding, while the third winding of the second inductor coil is configured to have a second mutual magnetic coupling with the first winding. The second winding is connected to the third winding such that the first mutual magnetic coupling and the second mutual magnetic coupling are in opposition. In this manner, the first inductor coil and the second inductor coil may be provided in a compact arrangement while providing weak mutual magnetic coupling between the first inductor coil and the second inductor coil.
