Analog Front-end Design of Passive RFID Tags for ISO/IEC 14443 and 15693

Abstract

This paper presents a design of analog front-end of passive RFID tags for ISO/IEC 14443 and 15693 by using SMIC 0.18μm 2P4M CMOS process. In order to have better performance, three rectifiers have been designed and compared, LDO and low-pass filter have been designed to obtain a high PSRR and a large range of subcarrier frequency respectively. As the post-layout simulation results showing, this design can satisfy both the ISO/IEC 14443 and 15693, and be adopted in many applications.
