Zusammenfassung:In one embodiment a method for communication using active load modulation in Radio Frequency Identification, RFID, systems comprising the following steps of receiving a carrier signal (Sc) having a carrier frequency from a reader device, generating a modulated signal (Smod), transmitting a burst of a sending signal (Sout), and decaying the sending signal (Sout) at the end of the burst. Furthermore, a transmitter circuit (T) for communication using active load modulation in RFID systems comprising an equipment (E1, E2, E3) for generating a decaying sending signal (Sout) is specified.
