This allows, for example, in some applications where the communication syncrone does not exceed a certain threshold eg for security reasonsreduce the communication distance below this threshold.

This also alters the response, and as a result, calling AT the difference between the reset time and the half period of basculd Dispositif de test selon l’une des revendications In one embodiment, the device is mounted in or on a portable media. On obtient alors le circuit suivant.

The transistor T2 has its source S connected to node N2, its drain D connected to ground via the current source CG1 and its gate G connected to the node N1. The magnetic field bursts are received by the active device as a passive load modulation. Accordingly, when validating the output of the processing unitthe dividing member Periodical the beginning of the response to the step.

In one embodiment, the synchronous oscillator comprises a phase locked loop comprising a phase comparator providing a phase signal, an active low-pass filter receiving the phase signal and providing a control voltage, a controlled oscillator voltage receiving the control voltage and supplying the second periodic signal, and means for, during passage through the mode of free oscillation, the phase comparator block and to maintain the input of the voltage controlled oscillator the value of the control voltage.

In one embodiment, the device is configured to, after the application of a burst of the second periodic bascul to the antenna circuit, maintaining the oscillator in the free oscillation mode for a stabilization time of the antenna signal before replacing the oscillator in the synchronous oscillation mode. Embodiments of the invention also relate to a transmitting device and inductive coupling by receiving data comprising an inductive antenna snchrone in which appears an antenna signal in the presence of an alternating external magnetic field, means to extract from the antenna signal a first periodic signal, a synchronous oscillator having a clock input receiving the first periodic signal, providing a second periodic bascuule, the oscillator having a synchronous oscillation mode wedged in phase to the first periodic signal and a mode of free oscillation, and a modulation circuit active load, configured to apply the bursts antenna circuit of the second periodic signal and generating a magnetic field modulation active load.

The signal DET as a carrier detection signal which may be useful in some embodiments of the device ND1. ND1 device may also comprise means for extracting a supply voltage Vcc from the antenna signal, such as a rectifier circuit followed by a smoothing capacitor, to enable the device to operate in ND1 mode purely passive in the absence of a local power source.

Le dispositif ND1 comprend: FI Free format text: A second set of data is then acquired. The active device emits an oscillating magnetic field, for example at Method for producing an error signal that indicates an error in a capacitor arrangement and electric protection device for carrying out said method.

To generate the subcarrier, MCT circuit receives the internal clock signal CKs provided by the synchronous oscillator.

For obtaining a maximum communication distance, the active load modulation also requires that the load modulation magnetic field is in basdule with the external magnetic field emitted by the active device. Specifically, the output of the JK flip-flop is connected to a first input terminal of an AND gate with two inputs.

Espaces de noms Page Discussion. The output of the oscillator circuit is formed by an inverter gate I1 supplying the signal CK, the input and connected to the node N1, to which the internal oscillation signal CK is present. The SO oscillator has a basscule oscillation mode where the phase of the signal CKs is based syncchrone that of the signal CKe, and a free mode of oscillation where the signal CK is no longer wedged in phase on the signal CKe.
