Abstract: The present disclosure relates to a near-field communication device including a near-field communication controller. The near-field communication controller includes at least one first demodulator, adapted to apply a first type of demodulation to a first signal modulated according to a first or a second type of modulation; and at least one second demodulator, adapted to apply a second type of demodulation to the first signal.

Abstract: A method includes detecting, by a first near-field communication device, the presence of a second near-field communication device. In a case where the second device is intended to be charged in near-field by the first device, the method further includes adjusting, by a control device, an impedance of an impedance matching circuit forming part of a near-field communication circuit of the first device.

Abstract: A first electronic device includes a first near-field communication antenna and a second near-field communication antenna. The first and second near-field communication antennas of the first electronic device are alternately activated. The first antenna is dedicated to supporting communication between the first electronic device and a second electronic device. The second antenna is dedicated to support charging of the second electronic device.
