Abstract: The present disclosure describes a circuit that includes a first inductor having a first terminal and second terminal, a second inductor having a third terminal and a fourth terminal, a first capacitor circuit, and a second capacitor circuit. The first and third terminals have a same polarity. The first capacitor circuit is cross-coupled to the first terminal and the fourth terminal. The second capacitor circuit is cross-coupled to the second terminal and the third terminal. The first and second capacitor circuits adjust an electrical coupling between the first and second inductor.

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.
