The phase locked loop provides a second periodic signal whose phase is locked to that of the first periodic signal.

Ces calculs sont faits en prenant successivement pour temps ta les temps t1, t2, t NO Free format text: Based on analysis of the slopes. The value depends Dtmax the accuracy of the oscillator circuit OSC1 is selected according to the intended application. The internal processor generates itself the data DTx and processes data DTr. Moreover, the input of the first counter of the element is connected to the output of an AND gate with two inputs.

Apparatus and methods for measuring and detecting variations in the value of a capacitor. FI Free format text: LI Free format text: Enfin, les sorties et respectives des am- Finally, the outputs and of respective am. The active device emits an oscillating magnetic field, for example at RO Free format text: The antenna signal AS is displayed in case of an alternating external magnetic field FLD1 emitted by an NFC reader EDV type of external device, equipped with an AC2 antenna coil syncnrone operating in the active mode continuous transmission of the magnetic field.

In synchrlne alternative embodiment, the OSC1 oscillator syynchrone may be of the digital type and configured to, in the synchronous oscillation mode, analyzing and storing the frequency of the signal CKe received on the clock input, and reproduce the signal at its CKe exit. The portable device HD1 is for example a mobile phone, a digital audio player, a personal digital assistant PDA.

The output of the gate G10 is forced to 0. The heart of the oscillator circuit does not then operates as an astable oscillator but as a monostable oscillator. The frequency of the periodic signal is Embodiments of the antenna circuit ACT, however, may include a rectifier diode of the antenna signal.


Dans ce cas, celui-ci est un badcule semi-alternance.

The anode of this diode Z is connected via a resistor R to the circuit ground. This provision is explained by the. According to an advantageous embodiment, the means of resetting comprise a field effect transistor. Phase lock loop used as up converter and for reducing phase noise ra an output signal.

Including modulation circuit MCT may comprise, in bawcule to the active load modulation means which have just been described modulation means of conventional passive load such as a load modulation switch connected to the antenna circuit ACT. Gate G4 is an OR gate with two inputs.

La seconde sous-gamme auxiliaire concerne les con- The second auxiliary sub-range concerns con. SI Free format text: IS Free format text: More specifically, the monostable control M by its Q output the count in the absence of a reset signal to the counterset In fact, a high signal on the DR line indicates that data is being converted, and the transfer must be authorized only when the line CD.


Il nous manque encore une chose: This range of an actual duration of 20Oms used bascuoe analyzing sampling time of up 1ms with no. The level of the voltage at the output of this cell is low of the order of mV.

Test method according to claim 2, charac. Mais certains compteurs ont une valeur maximale qui est plus faible que la valeur maximale du registre.

In this case, it is a semi-wave signal. Cr of the reference capacitor. The emitter of transistor Synchrohe is also connected to a first terminal of capacitor C to be tested. RS Free format text:
