用于温度日志标签的两级唤醒单元

A Two-stage Wakeup Unit for Temperature Logger Tag

设计实现了一个独特的两级唤醒单元,该唤醒单元用于基于EPC C1G2空中接口协议的射频识别标签。该标签为半有源标签,在该单元支持下实现温度日志功能。设计经过SMIC0.18μm EE工艺流片验证。测试结果表明标签实现温度日志功能,在1.8V电源电压下消耗150nA的静态电流,在同类工作中处于优势地位。

A novel two-stage wakeup unit is proposed for semi-passive temperature logger tag based on EPC C1G2 air interface protocol for RFID tags. This wakeup unit assists the tag to realize a temperature log function with a high sensitivity and low standby current level. It has been designed and fabricated in SMIC 0. 18 μm process as part of the whole tag. Measurement re-sults show that the tag can reduce the standby current to 150 nA.
