摘要

本論文為類比與數位所整合而成的電子標籤積體電路，目的是實現以SPI(Serial Peripheral Interface)為感測通信架構的無線生醫射頻應用，具有SPI介面的溫度感測器，可以透過本積體電路以RFID(Radio Frequency Identified Devide，無線射頻辨識裝置)的方式工作。電路設計方式分為兩部分來實現，第一部分是類比的部分，本論文晶片接收13.56MHz的射頻，並透過10% ASK 近場耦合的方式發射資料。晶片將接收到的能量，透過整流、穩壓得到工作所需的電能，同時也提供感測器工作所需的電能。第二部分，晶片感應到收發器發出的射頻訊號，產生工作所需的時脈，然後利用SPI協定和外接的SPI感測器通信，得到感測器的溫度資料。晶片以曼徹斯特編碼發射溫度資料。並接著發射因為這筆資料而產生的CRC code(循環冗餘檢查碼)，讓收發器驗證收到的資訊是否正確。在發射與接收的耦合為3%的條件下進行模擬，由TSMC 0.35μm 2P4M CMOS 製程來實現，電子標籤晶片含 I/O PAD 的面積為 1.379 × 0.922 mm2，Core的面積為 0.131 × 0.916 mm2。RFID的使用是未來的趨勢，但是如何讓RFID有更多的應用，是大家討論的重點。利用晶片面積的優勢，整合傳送與無線充電，並提供一個標準的通信介面，可以讓RFID的使用上有更大的利用空間。

The purpose of this thesis is illustrate the RFID Integrated Circuit which be combined by Analog and Digital for RF Biomedical Application. The sensor which with SPI Interface could operate as RFID (Radio Frequency Identified Device) through integrated. Circuit is divided into two parts to realize. The first, tag received the 13.56MHz Radio Frequency and sent out data by 10% ASK with near field coupling. At the same time, transmit the energy which get from tag pass to sensor. The last, chip get the RF signal from transceiver, and converted the clock to the SPI protocol and SPI sensor ext., get the temperature data after communicated. Send the temperature data by manchester coding, continued send the CRC code which be occurred by temperature data to make sure the information that transceiver have is right or wrong. Transmission System simulated term of 3% coupling. TSMC 0.35μm 2P4M CMOS process to produced. Chip including I/O PAD all area is 1.379 x 0.922 mm2 ,the core size is 0.131 x 0.916 mm2. Using RFID is the normal in future. But how to enlarge it, is the point of view.
