摘要:A current sensing circuit comprises a high frequency signal generator, anelectromagnetic exchanger, and a demodulation circuit. The high frequency signalgenerator generates a high frequency signal. The electromagnetic exchanger couples tothe high frequency signal generator, and receives the high frequency signal to generate a
high frequency magnetic field. The high frequency magnetic field modulates themagnetic field induced by a current to generate a modulated magnetic field. The
electromagnetic exchanger induces the modulated magnetic field to output a modulatedsignal. The demodulation circuit couples to the electromagnetic exchanger, and performsdemodulation to output a sensing result according to the modulated signal.
