The phase comparator receives, as reference frequency, a first periodic signal which is extracted from the antenna signal induced by the external magnetic field. Gate G4 is an OR gate with two inputs.

This provision is explained by the. Power transmitting device having device discovery and power transfer capabilities. Lapsed in a contracting state announced via postgrant inform.

The active load modulation consists of transmitting at the rate of the data carrier modulation signal bursts alternating magnetic field.

The oscillator is placed in a free oscillation mode during the application of the burst. The present invention relates generally to inductive coupling communication techniques also called “near field communication” or “NFC” Near Field Communications. Such syncchrone convert a sampled analog signal input.

ESR based on the following three substeps. A bascuke device according to one of claims. Two-point modulation type phase modulation apparatus, polar modulation transmission apparatus, wireless transmission apparatus and wireless communication apparatus.

Reference capacity of 10, pF. The method of claim 1 comprising the step of, after application of a burst of the second periodic signal CKs to the antenna circuit, maintaining the oscillator in the bascul oscillation mode for a stabilization time of antenna signal before replacing the oscillator in the synchronous oscillation mode. The present invention relates to a method for transmitting data by inductive coupling, comprising the steps of receiving an antenna signal by means of an inductive antenna circuit in the presence of an alternating external magnetic field, extracting signal antenna a first periodic signal, generating a second periodic signal by means of a synchronous oscillator having a clock input receiving the first periodic signal, syynchrone oscillator placed in one mode of free oscillation and to apply bursts of the antenna sychrone of the second periodic signal for generating a magnetic field modulation active load.

A method for transmitting data by inductive coupling, comprising the steps of: Although the signal CKs is synchronized with a fairly good precision to the external clock signal CKe, the phase difference between the induced signal and the injected signal may be sufficient to cause a phase fluctuation making it unfit antenna signal to provide a signal CKe reliable external clock.

The phase locked loop comprises a VCO voltage controlled oscillatora phase comparator and a low pass filter supplying a control voltage to the VCO.

It may therefore be desirable to provide a means for providing magnetic field bursts synchroen have low phase shift with respect to the external magnetic field, without using an extremely precise circuitry and costly to achieve.

When the DET signal is equal to 1 presence of an external magnetic field FLD1the output of the gate G3 is set to synhcrone and the device operates in a passive mode as described above.
