1. A wireless power receiver comprising:

  • a receiver resonator coupled to an impedance matching network, the impedance matching network having a first node and a second node;

    coupled to the first node, a first branch having a first positive reactance and a second branch having a first negative reactance, wherein an absolute value of the first positive reactance is different from an absolute value of the first negative reactance; and

    coupled to the second node, a third branch having a component with a second positive reactance and a fourth branch having a second negative reactance, wherein an absolute value of the second positive reactance is different from an absolute value of the second negative reactance;

    a first rectifier having a first rectifier input coupled to the first branch;

    a second rectifier having a second rectifier input coupled to the second branch;

    a third rectifier having a third rectifier input coupled to the third branch; and

    a fourth rectifier having a fourth rectifier input coupled to the fourth branch.
