An analog front-end IP for 13.56MHz RFID interrogators

An analog front-end circuit for 13.56MHz RFID interrogators compatible with ISO 14443, ISO 15693 and ISO18000-3 Mode 1 RFID interrogators was designed and fabricated by using 0.35/spl mu/m double poly CMOS process. The fabricated chip was operated at 3.3 volt single supply. The results of this work can be provided as reusable IPs in a form of hard or firm IPs for designing single chip 13.56MHz RFID interrogators.
