The invention relates to an integrated circuit for contactless radiofrequency device connected to a first antenna and to a second antenna designed to receive a radiofrequency signal coming from a reader. According to a main characteristic, the integrated circuit includes 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 V 1 and V 2 , the rectifier circuits being mounted in parallel in order to select an output voltage value that corresponds to the maximum voltage value between V 1 and V 2.
