Abstract
A system includes a power receiver including an oscillator with a first coil and a second coil. The oscillator includes a first field effect transistor (FET) having first gate, first source, and first drain terminals, the first drain terminal coupled to the first coil, the first coil adapted to be inductively coupled to a third coil in a power transmitter. The oscillator also includes a first capacitor coupled to the first coil. The oscillator includes a second FET having second gate, second source, and second drain terminals, the second gate terminal coupled to the first capacitor, the second source terminal coupled to the first source terminal, and the second drain terminal coupled to the second coil, the second coil adapted to be inductively coupled to a fourth coil in the power transmitter. The oscillator includes a second capacitor coupled to the first gate terminal and coupled to the second coil.
