Abstract: A near field communication (NFC) method includes activating an NFC device second device in response to a first electromagnetic field generated by a nearby NFC device. The NFC device generates a second electromagnetic field after being activated. The first NFC device can detect the second electromagnetic field and initiate a near field communication process.

Abstract: A method for decoding a data stream carried by a modulated signal includes receiving the modulated signal. The modulated signal is modulated according to a protocol belonging to a group of protocols including at least three protocols. The method further includes extracting a clock signal from the received modulated signal, detecting the protocol, and decoding the data stream according to the detected protocol using the extracted clock signal.

Abstract: In some embodiments, a contactless communication device includes an antenna, and a driving stage having a power supply terminal configured to receive a power supply voltage, where the driving stage is configured to deliver a current to the antenna. The device further includes a monitoring circuit configured to monitor the power transmitted by the antenna. The monitoring circuit is configured, in the presence of a request for a reduction in a current level of transmitted power, to reduce the power supply voltage of the driving stage down to a target value corresponding to a new level of the transmitted power less than the current level.

Abstract: A method of wireless communication includes transmitting frames from a transponder to a reader and synchronizing between a reader carrier frequency and an active load modulation (ALM) carrier frequency within each transmitted frame. Each transmitted frame includes ALM carrier bursts generated from subcarrier modulation by binary phase shift keying (BPSK) data encoding and producing signal oscillations at a transponder antenna after each ALM carrier burst generation, The synchronizing occurs at each phase change of the data encoding when no burst is generated during a half period of the subcarrier preceding the phase change and a half period of the subcarrier following this phase change. The transponder antenna has a moderate quality factor sufficient to naturally damp the signal oscillations so that the synchronizing is performed without performing any controlled signal oscillations damping.
