Patent ID: 8702008

Claim:
An RFID transponder chip, which includes: at least one antenna to pick-up radio-frequency signals, a rectifier to store charge on at least one capacitor at a rectified voltage from the picked-up radio-frequency signals, a power-on reset circuit to maintain a logic unit in a reset state if the rectified voltage level is less than a power-on reset or wake-up voltage level of the power-on reset circuit above which the logic unit can operate, wherein the RFID transponder chip further includes a non-volatile memory, in which are stored one or several trim power-on reset values, said non-volatile memory being directly connected to the power-on reset circuit in order to be able to provide directly at least one trim power-on reset value to trim the power-on reset circuit, first when the rectified voltage increases after the reception of radio frequency signals and at a rectified voltage level below a wake-up voltage level.
