An NFC transceiver using an inductive powered receiver for passive, active, RW and RFID modes

摘要

This paper present a transceiver for NFC (Near Field Communication) using an inductive powered receiver to enable all type of NFC communication modes such as the passive, active, RW, and RFID modes. Notably, when the external battery has been fully discharged, the RFID mode can be operated through the inductive powered structure. We have analyzed the capacity of the inductive powered receiver of the NFC transceiver to achieve power from an RF Signal for an RFID mode. To understand the range of power available, we have simulated the harvesting of power from a loop antenna at 13.56 MHz. The bandwidth of the receiver is designed to range from 106 kbps to 424 kbps even to a 867 kHz subcarrier of 13.56 MHz RFID tag.
