RFID Radio Circuit Design in CMOS: White Paper

ABSTRACT
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 lowpower
integrated circuit integrated with an inexpensive
printed antenna. Details on the design of the rectifi er
power regulator, demodulator, reset circuit, modulator,
and antenna are highlighted. The paper includes a
system-level software verifi cation of the RFID tag system
to determine proper voltage regulation and signal
demodulation.
