A system for tuning an impedance at a node comprises a first component associated with a first impedance when the first component is operating and a second impedance when the first component is not operating. The system further comprises a second component coupled to the first component at a node. The second component is associated with a third impedance when the second component is operating and a fourth impedance when the second component is not operating. An impedance tuning circuit is coupled to the second component at the node and operable to tune an impedance at the node based at least in part upon a plurality of the first impedance, the second impedance, the third impedance, and the fourth impedance.
