摘要

本論文為設計一個應用於無線心律擷取系統之無線射頻標籤基頻收發機，第一部分為讀取端系統之數位控制電路，電路包含：脈衝間隔編碼電路將欲傳送之數位訊號編碼後給予無線射頻前端電路發送、超取樣資料擷取電路將無線射頻前端接收下來的數位訊號準確地解調、雙向間隔空間解碼電路將解調後的訊息還原、循環冗餘檢查電路檢查訊息的正確性。第二部分為標籤端系統之數位控制電路，電路包含：脈衝間隔解碼電路解調接收到的無線訊號、隨機亂數產生電路產生隨機亂數供電路使用、循環冗餘檢查電路在資料內加入檢驗碼、雙向間隔空間編碼電路將欲傳送之資料進行編碼、記憶體讀寫控制電路將感測到的生理資訊儲存至記憶體中並供電路讀取使用。

而本論文之標籤端基頻處理器採用TSMC 0.18µm 1P6M CMOS標準製程實現晶片，整體電路面積0.866mm2。讀取器端基頻處理器採用ALTERA公司提供之FPGA實現。

In this thesis, a baseband transceiver of RFID is designed for wireless acquisition. Digital controller of system is composed of reader and tag. Reader was divided into four parts. One is pulse interval encoding encoder, encodes digital data before the data is transmitted by radio frequency front-end circuit. Another is oversampling circuit, demodulates digital data correctly. Another is bi-phase space encoding circuit, recovers demodulated data. The other is cyclic redundancy check circuit, checks whether the data is correct. Tag includes five parts. Pulse interval encoding decoder decodes the data from RF front-end. Pseudorandom Random Number Generator supplies a random number for other circuit. Cyclic redundancy check circuit adds check code to the data. Bi-phase space encoding circuit encodes the data before the data is transmitted. Read and write controller saves ECG to memory.

In baseband processor of tag, TSMC 0.18μm 1P6M CMOS process was used to implement the integrated circuit. The total chip area is 0.866 mm2. And in baseband processor of reader, ALTERA FPGA was used.
