RFID Radio Circuit Design in CMOS

This paper describes a reference design with circuits and an antenna for a UHF RFID system. A new Class 2 (Gen 2) tag was designed, including the extremely low power integrated circuit integrated with an inexpensive printed antenna. Details on the design of the rectifier power regulator, demodulator, reset circuit, modulator, and antenna are highlighted. The paper includes a system-level software verification of the RFID tag system to determine proper voltage regulation and signal demodulation.
