| 摘 要： | INTRODUCTION The rapidly increasing application of radio fre- quency identification (RFID) includes supply chain management, access control to buildings, public transportation, airport baggage, and express parcel logistics (Karthaus and Fischer, 2003; Feldhofer, 2004; Glidden et al., 2004). Using an RFID system is a good approach for automated identification of products. RFID system consists of two major components, an interrogator (reader) and a transponder (tag), composed of an ant…

| Abstract: | The 13.56 MHz analog front-end circuit for ISO/IEC 15693-compatible radio frequency identification (RFID) transponder IC presented in this paper converts RF power to DC and extracts clock and data from the interrogator by 10% or 100% ASK modulation. The transponder sends data back to the interrogator by load modulation technology. The electrostatic discharge (ESD) protection circuits function to limit RF voltage to a safe level. An inductive coupling simulation modelling for 13.56 MHz RFID system is presented, with simulation results showing that the transponder operates over a wide range of electromagnetic field strength from H min (150 mA/m) to H max (5 A/m). The transponder IC is implemented in SMIC 0.35-μm three-metal two-poly mixed signal CMOS technology with embedded EEPROM. |
