Abstract: The present invention discloses an isolator and a signal generation method. The isolator includes an input-side circuit, an output-side circuit and a signal transmission unit. The input-side circuit is configured to receive an input signal and to generate an encoding signal according to the input signal. The signal transmission unit is coupled to the input-side circuit and configured to receive and transmit the encoding signal. The output-side circuit is coupled to the signal transmission unit and configured to receive the encoding signal from the signal transmission unit. The encoding signal includes a first portion and a second portion. The first portion is a pulse signal, and the second portion is a non-amplitude encoding signal.

Abstract: A current sensing circuit comprises a high frequency signal generator, an electromagnetic exchanger, and a demodulation circuit. The high frequency signal generator generates a high frequency signal. The electromagnetic exchanger couples to the high frequency signal generator, and receives the high frequency signal to generate a high frequency magnetic field. The high frequency magnetic field modulates the magnetic field induced by a current to generate a modulated magnetic field. The electromagnetic exchanger induces the modulated magnetic field to output a modulated signal. The demodulation circuit couples to the electromagnetic exchanger, and performs demodulation to output a sensing result according to the modulated signal.
