Abstract: A reconfigurable amplifier load includes a power supply node, a first inductor comprising a first terminal coupled to a first switch, and a second inductor comprising a first terminal coupled to a second switch. The reconfigurable amplifier load further includes a third inductor comprising a first terminal coupled to the first switch. The first switch is configured to selectively couple the first terminal of the third inductor to the power supply node. A fourth inductor comprising a first terminal coupled to the second switch. The second switch is configured to selectively couple the first terminal of the fourth inductor to the power supply node. At least one additional switch configured to selectively couple a second terminal of the first inductor or a second terminal of the second inductor or both the second terminal of the first inductor and the second terminal of the second inductor to the power supply node.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus employing an isolation ring having a center strip of conductive material used to isolate magnetic fields generated by common-mode and differential-mode current flow through one or more inductors disposed in the ring. The apparatus generally includes an electrical component having an inductive element and a ring of electrically conductive material encircling the inductive element, wherein the ring has a strip of electrically conductive material disposed in the ring and connecting a first point on the ring to a second point on the ring.
