发明名称 DEVICE WITH NO RADIOFREQUENCY CONTACT COMPRISING SEVERAL ANTENNAS AND ASSOCIATED ANTENNA SELECTION CIRCUIT.
摘要 <p>The invention relates to an integrated circuit for a device with no radiofrequency contact connected to a first antenna and to a second antenna designed to receive a radiofrequency signal from a reader. According to a main characteristic, the integrated circuit comprises a first rectifier circuit and a second rectifier circuit to rectify each radiofrequency signal received from the first antenna and the second antenna, respectively, so as to produce two positive output voltages Vl and V2, the rectifier circuits being mounted in parallel so as to select an output voltage value corresponding to the maximum voltage value between Vl and V2.</p>
