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.
