Embodiment Construction

[0032] In the various drawings, like features are designated by like reference numerals. In particular, structural and / or functional elements common to different embodiments and implementations may be designated with the same reference numerals, and may have the same structure, size, and material properties.

[0033] For clarity, only those steps and elements that are useful for understanding the described embodiments and modes of implementation are shown and will be described in detail. In particular, the generation of radio-frequency signals and their interpretation are not detailed, and the described embodiments and modes of implementation are compatible with common techniques for the generation and interpretation of such signals.

[0034] Unless otherwise indicated, when reference is made to two elements connected together, this means a direct connection without any intervening elements other than conductors, and when reference is made to two elements coupled together, it ...

Abstract

The embodiment of the invention relates to near field communication equipment and a near field communication method. A method includes detecting, by a first near field communication device, the presence of a second near field communication device. In case the second device is intended to be charged in the 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.

Description

technical field [0001] The present disclosure generally relates to electronic devices. The present disclosure relates more particularly to electronic devices integrating near field communication circuitry (NFC), more commonly referred to as NFC devices, and near field communication devices implemented by these devices. Background technique [0002] In addition to near-field data exchange methods between NFC devices, NFC devices are known which are capable of implementing near-field power transfer methods aimed at charging an NFC device with another NFC device. However, such NFC devices become complicated, bulky and expensive. Contents of the invention [0003] There is a need for improvements in near field communication devices and known communication methods thereof. [0004] Embodiments overcome all or some of the disadvantages of near field communication devices and known communication methods thereof. [0005] The embodiment provides a method, comprising the followi...
