摘要

此論文提出可搭配感測器的超高頻925MHz無線射頻辨識系統標籤，此次提出的射頻辨識系統主要包含整流器、編碼器、解碼器、Power-On-Reset和邏輯控制內的暫存器。標籤所需電源完全由天線所接收到的功率經由整流器轉換提供。標籤的天線在距離讀取機5公尺處，最多能接收到180uW。其晶片消耗功率約為57uW，本設計皆符合Gen-2的規格。使用的製程為TSMC 0.35um CMOS 2P4M標準製程，晶片大小為0.7*0.57um2。

In this thesis, a passive UHF 925MHz RFID tag for RF-sensor is presented. The proposed RFID tag circuit includes the CMOS RF to DC rectifier, ASK demodulator, ASK modulator, logic and control circuit, and power on reset. The 925MHz RFID tag matches the EPC Gen-2 specifications, where the data rate is 640K/s. The maximum power that the tag received is 180uW. The totally power consumption of the tag in this work is 57uW, and it is totally supplied from the antenna received. This whole circuit is implemented in the TSMC 0.35um CMOS 2P4M standard process, and its size is 0.7*0.57um2.
