Abstract
An apparatus for wireless power reception includes a receiver coil and a rectifier having a first input and a second input, the first input coupled to a first terminal of a receiver coil, the second input coupled to a second terminal of the receiver coil through a resonant capacitor. The apparatus further includes a first capacitor and a first switch network connected in series between the first input and ground and a second capacitor and a second switch network connected in series between the second input and ground, each of the first switch network and the second switch network including at least a plurality of field-effect transistors (FETs) connected in parallel, wherein the first switch network and the second switch network configured to adjust an impedance coupled to the receiver coil, the impedance associated with an Amplitude Shift Keying (ASK) modulation used by the apparatus.
