Abstract :
A nano-power power-on-reset (POR) circuit for passive RFID tag is presented in this paper. It is applied to a passive UHF C1G2 RFID tag ICs fabricated in a 90-nm CMOS technology. Measurement results confirm that the generated POR pulse signal is accurate and reliable due to the proposed hysteresis-comparator structure and power-off auto-discharging path. Moreover, the POR circuit consumes 150-nA quiescent current only.
