The invention relates to an integrated circuit for a device with no radio frequency contact connected to a first antenna and to a second antenna desig ned to receive a radiofrequency signal from a reader. According to a main ch aracteristic, the integrated circuit comprises a first rectifier circuit and a second rectifier circuit to rectify each radiofrequency signal received f rom the first antenna and the second antenna, respectively, so as to produce two positive output voltages Vl and V2, the rectifier circuits being mounte d in parallel so as to select an output voltage value corresponding to the m aximum voltage value between Vl and V2.
