Abstract: Techniques for isolation between filters using inductive coupling cancellation are disclosed. An apparatus includes a first filter including a first plurality of inductors and a second filter including a second plurality of inductors. The first and second filters are implemented physically adjacent to one another. First and second ones of the first plurality of inductors and a first one of the second plurality of inductors are polarized in a first direction, while a second one of the second plurality of inductors is polarized in a second direction opposite that of the first direction. The second one of the second plurality of inductors is physically adjacent to one of the first and second ones of the first plurality of inductors such that magnetic coupling currents induced into one another are canceled.

Abstract: The present disclosure describes a semiconductor structure that is resistant to induced eddy currents. The semiconductor device includes a substrate, a device layer having electronic devices on the substrate, and a metallization layer above the device layer. The first metallization layer includes first and second terminal traces, a switch, and capacitors. A first terminal of a capacitor of the capacitors is coupled to the first terminal trace via the switch. A second terminal of the capacitor is coupled to the second terminal trace. The first and second terminal traces are disposed along the same side of the capacitors.
