More Information
Summary:A voltage limiter incorporated in a radio frequency identification -RFID- integrated circuit -IC- for a RFID tag is disclosed. The RFID IC includes a radio frequency -RF rectifier (112) and a clock generator. The RF rectifier (112) is configured to convert an AC signal received from an antenna incorporated in the RFID tag to a DC signal (Vrec). The voltage limiter includes a current sink device (116) coupled between output of the RF rectifier (112) and ground and a charge pump (114) to control conduction of current through the current sink device (116) to limit output voltage (Vrec) of the RF rectifier (112) to a predefined voltage level.
