摘要/Abstract：

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