中文摘要	A self-adaptive current mode amplitude shift-keying (ASK) demodulator was proposed to meet the requirements of the low-voltage RFID tags. The demodulator improves the dynamic demodulation performance by converting voltage signal to more detectable current signals, employing two-stage current-peak- hold technique, and introducing leak circuit. It could operate under the supply voltage from 0.6 V to 1.8 V, the input carrier magnitude is from 250 mV to 1.1 V, and the modulation depth is from 20% to 100% . Under the voltage supply of 1.8 V, its dynamic demodulation is from 80 nA to 3.96 mu A. The demodulator is designed and implemented with 0.18 mu m CMOS process technology.
