Design of the Digital Circuit for a UHF RFID Tag
Bin Liao · Semiconductor Technology · 2007
On the basis of research on the communication between reader and tag,a digital circuit applied in UHF RFID tag was designed by VHDL language according to the EPC C1G2 and ISO/IEC18000-6 protocols.The system architecture and the design of each module were performed.Based on 0.18 μm CMOS standard cell library,the front-end synthesis and back-end implementation were developed using the EDA tools.Results from simulations indicate that the function of the circuit matched the protocol.The chip after synthesizing is about 11000 gates with a power consumption of 35 μW.The circuit can be applied into various UHF RFID tags.
