A band-gap reference for 13.56 MHz passive RFID tag IC is realized based on the traditional band-gap voltage reference structure. This circuit is fabricated by using SMIC 0. 18 /μm CMOS mix-signal technology. When the supply voltage ranges from 4.0 V to 11.0 V, the output voltage is 1. 165 ± 0. 004 V. Within the temperature range of -40-100 ℃ and under the supply voltage of 7 V, the temperature coefficient is 18.3× 10-6℃ and the start-up time of the band-gap is 6.8 μs.
