A tuner and rectifier circuit for wireless power transfer receivers is provided using a single inductor and two switching networks. The single inductor is used for energy exchange between the receiver resonant circuit and an output energy buffer network wherein the rectification function is met. The tuning state of the receiver resonant circuit is tracked and the inductor is accordingly coupled with the receiver resonant circuit after an adaptive time period to inject an inductive reactance to the tank for tuning purpose.
