Abstract (en)
[origin: WO2008065003A1] Electronic device (1) for radio frequency identification and method for adjusting the resonance frequency of said electronic device comprising a chip (23) equipped at least with at least one modulation capacitor (9), a rectifier (11), a memory unit (13) and a logical control unit (15); a resonant tank (20), connected to said chip, which comprises at least one inductor (2),- and at least one resonance capacitor (3); and a load capacitor (4) for supplying power to said device. Said chip comprises a thick trimming circuit (21) for adjusting the resonance frequency of the device, which comprises a plurality of integrated capacitors (5.1 / 5.m) that can be connected in parallel to the resonance capacitor,- and a thin trimming circuit (22) for adjusting the resonance frequency of the device, which comprises a plurality of integrated capacitors (5m+1 / 5m+n) that can be reversibly connected or disconnected in parallel to the resonance capacitor.
