Abstract
An embodiment of a RF identification device is formed by a tag and by a reader. The tag is formed by a processing circuit and a first antenna, which has the function both of transmitting and of receiving data. The reader is formed by a control circuit and by a second antenna, which has the function both of transmitting and of receiving data. The processing circuit is formed by a resonance capacitor, a modulator, a rectifier circuit, a charge-pump circuit and a detection circuit. The antenna of the tag and the processing circuit are integrated in a single structure in completely monolithic form. The first antenna has terminals connected to the input of the rectifier circuit, the output of which is connected to the charge-pump circuit. The charge-pump circuit has an output connected to the detection circuit.
