Abstract: An electronic device for wirelessly transmitting power includes a first coil assembly; a second coil assembly; and a processor configured to control to generate a first magnetic field by applying first current to the first coil assembly; obtain a plurality of first sensing values of the first magnetic field sensed by a plurality of coils included in the second coil assembly; and identify whether a foreign material exists in a power transmission area of the electronic device based on the plurality of first sensing values.

Abstract: A host interface includes; a phase shift detector, a phases shifter, and control logic controlling operation of the phase shift detector and the phase shifter. The host interface sends a command and a clock to a device, receives a response from the device, communicates data to the device synchronously with the clock, and samples data received from the device synchronously with a modulated clock. The phase shift detector provides a shift value based on the response, and the phase shifter modulates a phase of the clock based on the shift value to generate the modulated clock.
