Several key issues including system noise figure, input linearity, LO phase noise performance and transceiver setting-up time are recapitulated in this paper for the design of single-chip UHF RFID reader. The reader Rx noise figure is different between LBT and normal mode. The input linearity is decided by the maximum interferer due to Tx-to-Rx leakage. Phase noise requirements are to meet with Tx...
A novel single-chip 860-960MHz band UHF RFID reader transceiver IC is fabricated in 0.18μm CMOS technology. The transceiver consists of a compact high-linearity low-noise-figure RF front-end, a programmable analog baseband for Rx path; and an image reject filter, a PGA, a switchable up-conversion modulator and a driver amplifier for Tx path. The 3-bit 3rd-order DSM fractional-N frequency synthesizer...
