A 13.56MHz receiver SoC for multi-standard RFID reader

A HF (13.56 MHz) RFID receiver architecture SoC (System on Chip) is proposed. The receiver can be used in the standards of ISO/IEC 14443 type A/B, 15693, and 18000-3. Before designing the circuit, standard analysis is processed. And also, we did a previous measurement for preparing implementation as a chip level. That is, a RFID transceiver test board using commercial components was configured and tested. Through the board experiments, we checked the possibilities of operation of designed receiver. Based on the experiment results, the multi-standard 13.56 MHz RFID receiver SoC was designed and fabricated using TSMC 0.18 um CMOS technology. The test results show that designed receiver system as a chip level can be operated properly in multiple standard conditions.
