RFID SYSTEM THAT INCLUDES A HYBRID RFID TAG

This disclosure is generally directed to an RFID system that includes a hybrid RFID tag offering a functionality of a passive RFID tag and an active RFID tag. When operating as a passive RFID tag, an RF signal received from an RFID reader is harvested to produce a DC voltage for powering the hybrid RFID tag. The harvested DC voltage is coupled into a capacitor at a slow-charging rate so as to avoid a capacitor inrush current causing an abrupt power supply voltage drop. A controller chip in the hybrid RFID tag can execute some RFID functions at this time, thereby speeding up a response to the RFID reader. The capacitor is then charged at a fast-charging rate for storing a reserve charge. The hybrid RFID tag can subsequently use the reserve charge to operate as an active RFID tag without waiting for an RF signal from the RFID reader.
