Abstract

An analog front-end circuit for 13.56MHz ISO/IECl4443 type B compatible RFID tags was designed. The designed circuit includes a rectifier and regulator to generate a stable DC voltage from the RF signal, an over-voltage limiter to protect the circuit from high voltages, an ASK demodulator to extract the data transferred from reader to tag, and a load modulator to transfer data from tag to reader. The functionality of the designed circuit has been verified through simulations using 0.25um CMOS process parameters.
