This paper presents in details the architecture and most of RF front-end building blocks of a fully integrated passive radio frequency identification (RFID) transponder operating at UHF 902 MHz to 928 MHz. A novel architecture for the transponder IC and a new low power on-off keying (OOK) demodulator are proposed in this paper. For realizing the system, a low power CMOS full-wave rectifier achieving...
Nowadays the implementation of highly integrated UHF RFID reader transceiver RF front-ends with excellent performance is demanding and is still challenging. This paper presents a number of design considerations from the system point of view, including the choice of receiver/transmitter front-end architecture, isolation between transmitter and receiver, power efficiency of the transmitter. Some critical...
With the recent explosive growth of the market demand for RFID systems, design of RFID tag and reader IC has become one of the most popular research areas. This paper gives a review of several key issues in the UHF RFID tag and reader design. To achieve a higher identification performance, a low cost, low power RFID tag with efficient anti-collision technique which provides a large throughput and...
This paper presents a novel space division transponder anti-collision algorithm for RFID system, which has been implemented in a passive transponder. Working at 915 MHz carrier frequency with 4W effective isotropic radiated power (EIRP) from a reader, the tags can be distinguished by their diverse distances to the reader if the distance difference is larger than 0.11 m with communication range from...
The operating principle of typical MOSFETs AC/DC rectifier is introduced in this paper. In order to maximize the operating range of RFID transponder, low-power design techniques are needed. Therefore, the key design parameters optimization of passive rectifier is discussed. Besides, the design of a low-power rectifier for passive UHF RFID transponder, which is compatible with standard CMOS process...
The operating principle of MOS FETs AC/DC rectifier for passive RFID transponder is introduced and the power dissipation of MOS rectifier operating with 902M-928MHz industrial, scientific, and medical (ISM) carrier frequency is presented in details in this paper. In order to maximize the operating range of RFID transponder, low power design techniques are needed. Therefore, the key design parameters...
