Abstract

In this paper a Fractional-N frequency synthesizer is designed for UHF RFID readers. It satisfies the ISO/IEC frequency band $(860{\sim}960MHz)$ and is also applicable to mobile RFID readers. It is designed using a $0.18{\mu}$ RF CMOS process. The measured results show that the designed circuit has a phase noise of -103dBc/Hz at 100kHz offset and consumes 9mA from a 1.8V supply. The channel switching time of $10{\mu}s$ over 5MHz transition have been achieved, and the chip size including PADs is $1.8{\times}0.99mm^2$
