Abstract
A specific absorption rate detection assembly, an SAR detection method, and an electronic device are provided. The SAR detection assembly includes a sensing branch, a detection branch, an SAR sensor, and a compensation branch. The sensing branch is configured to sense a capacitive signal. The detection branch is configured to generate a first noise signal by sensing ambient noise. The capacitive signal and the first noise signal are transmitted to the SAR sensor by the detection branch. A first end of the compensation branch is connected to a reference power-supply terminal. The compensation branch is configured to generate a second noise signal by sensing ambient noise and transmit the second noise signal to the SAR sensor. The second noise signal is used to simulate the first noise signal to compensate, through the second noise signal, the capacitive signal and the first noise signal transmitted to the SAR sensor.
