Abstract
A RFID transponder includes an active load modulation unit and an energy harvesting unit coupled to the active load modulation unit. The active load modulation unit performs active load modulation on transmitted signals. The energy harvesting unit harvests RF energy from the ambient environment, converts the RF energy to DC energy, stores the DC energy, and supplies the DC energy to the active load modulation unit.
