摘要
The present invention relates to systems and methods for operating an RFID transponder (102). The methods include performing energy harvesting operations by the voltage scavenging device 130 of the RFID transponder to collect energy from the RF field, magnetic field, heat, light or motion of the RFID transponder; Increasing or decreasing, by a voltage converter of the RFID transponder, the voltage level of a signal received from the voltage scavenging device to a sub-threshold voltage level that is at least 10 times less than the normal operating range for the RFID transponder; And supplying an operating voltage at a sub-threshold voltage level to at least the transceiver circuit (124) of the RFID transponder.
