Abstract
Various embodiments are directed to apparatuses and methods related to source circuitry that provide power to other circuitry. The source circuitry including gain circuitry and a source resonator. The gain circuitry provide powers to the source resonator with a gain that is dependent on a coupling rate between the source circuitry and other circuitry. The source resonator is coupled to the gain circuitry and generates a magnetic field in response to the power. The source circuitry is configured and arranged to wirelessly transfer the power to the other circuitry via the magnetic field.
