A two-stage wake-up circuit for semi-passive radio frequency identification (RFID) tag is designed and implemented in SMIC 0.18 ¿m CMOS technology. In order to prolong the tag's battery life, a novel two-stage wake-up strategy with self-calibration is proposed. Measurement results show that the wake-up circuit has no static power and is free of process, voltage and temperature (PVT) variations.
