Abstract: A dual frequency HF-UHF RFID integrated circuit including a power supply. The power supply includes: an HF branch including an HF rectifier and a linear voltage regulator, wherein the HF rectifier is configured to be connected to a resonance circuit formed by a HF antenna-coil and a resonance capacitor and wherein the HF rectifier is connected to the linear voltage regulator; a UHF branch including a UHF rectifier and a shunt voltage regulator, wherein the UHF rectifier has a charge pump and is configured to be connected to a UHF antenna and wherein the UHF rectifier is connected to the shunt voltage regulator; and a supply line, wherein the linear voltage regulator and the shunt voltage regulator are both connected to the supply line of the power supply.

Abstract: An RFID assembly and an assembly method thereof are provided. The assembly method for an RFID assembly comprises a step of providing at least one integrated circuit which includes at least one IC contact and at least one dielectric layer, and a deposition of at least one electrical contact and of at least one re-passivation layer. The at least one electrical contact is deposited on at least one first portion and the at least one re-passivation layer is deposited on at least one second portion, which is distinct of the at least one first portion.
