Method for adjusting output of amplifier by using sensing circuit configured to sense power supplied to amplifier and electronic device therefor
An electronic device is provided. The electronic device includes an antenna, an amplification circuit configured to amplify a signal to be transmitted through the antenna, a first sensing circuit configured to sense first information corresponding to a voltage value of power supplied to the amplification circuit, a second sensing circuit configured to sense second information corresponding to a current value of the power, and a protective circuit. The protective circuit may be configured to summate the first information and the second information into a single parameter, to determine whether a summation value corresponding to the single parameter deviates from an operating area determined by characteristics of the amplification circuit, and to adjust an output of the amplification circuit if the summation value deviates from the operating area.
