Abstract :
A novel low power temperature sensor of strong power supply variation rejection ability for passive RFID tags is presented. As a resource reuse method adopting by the proposed temperature sensor, it has lower power consumption and stronger power supply variation rejection ability than the conventional temperature sensor. The sensor features a low power consumption of 3 ¿W, while the maximum error caused by power supply variation is only 0.95°C.
