Abstract :
A passive UHF RFID tag LSI in 0.35mum CMOS with 2kb FeRAM enables the 2.9-times higher 32b read-and-write throughput over an EEPROM-based tag. A CMOS full-wave rectifier improves the power efficiency from 16.6% up to 36.6% by lossless internal Vth cancellation and mirror stack architecture. A current-mode ASK demodulator converts the 15% power modulation into linear current signal over a 27dB dynamic range of the incoming power
