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.

RFID assembly and assembly method thereof

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.

Dual frequency HF-UHF identification integrated circuit

A method and device for transmitting () to an electrical element () the power of a radio frequency type signal received by a radio frequency receiver (), e.g., a radio frequency identification (RFID) chip, the receiver () having a receiving antenna () and a voltage rectifier () of the signal received by the antenna (), the transmission device () including a voltage converter () connected to the rectifier () of the chip and to the electrical element (). The device includes a control system () configured to momentarily derive the signal from the rectifier () in order to define an optimal input voltage of the converter () for which the input impedance of the converter corresponds to the output impedance of the rectifier (), and to redirect the DC signal to the voltage converter () by providing the converter with an input voltage setpoint corresponding to the optimal voltage.

Method and system for transmitting the power of a radio frequency type signal received by a radio frequency receiver

An integrated circuit chip (), an antenna () and a tamper loop (), and in addition to this, a light emitting diode (LED) (), configured to be activated, i.e. supplied with current, upon a signal received by the antenna (). The LED () is integrated in the device in such a way that when the LED is activated in the above-described way, the LED lights up so as to become visible by the naked eye, on the condition that the tamper loop () is in a predefined state, either open or closed. The LED () is coupled between the same terminals () of the integrated circuit chip () as the tamper loop ().

Tamper detection device

A receiver unit for a radio frequency (RF) tag is provided, including a first input terminal and a second input terminal each being connected to an antenna; a communication stage configured to demodulate and/or to modulate an incoming signal in the communication stage; and a power stage including a voltage converter circuit being configured to supply power to the receiver unit, and a regulation circuit being configured to limit an output voltage of the voltage converter circuit, wherein the regulation circuit includes a regulator circuit being configured to determine a first current value and a second current value, the second current value being a current value provided in addition to the first current value, and, if the second current value exceeds a predetermined threshold value, to supply a control signal to a limiter circuit configured to limit an input voltage of the voltage converter circuit.
