Design of 2.45GHz Passive RFID Transponder with Injection-Locked VCO

[[abstract]]在本論文中，設計與實現一個使用注入式栓鎖壓控振盪器之2.45GHz被動式RFID詢答器晶片，詢答器晶片包含五個部份：RF-to-DC轉換器、模式選擇器、壓控振盪器、數位控制電路及數位調變電路。將2.45GHz峰值電壓為250mV的外來訊號以直接注入方式輸入至注入式栓鎖壓控振盪器，可使輸出振盪頻率鎖於2.45GHz，其頻率的栓鎖範圍為206MHz。晶片內含128位元唯讀記憶體，且資料傳輸速度可達153Mb/s。晶片採用國家晶片系統中心(CIC)提供的TSMC 0.18μm 1P6M CMOS製程進行設計與實現，晶片面積大小為479μm × 627μm。晶片工作於1V時，功率消耗為3.82mW。[[abstract]]In this thesis, a 2.45GHz passive RFID transponder with injection-locked VCO is presented. The RFID transponder contains five parts: the RF-to-DC converter, the mode selector, the injection-locked voltage-controlled oscillator(ILO), the digital control circuit and the digital modulator. The injection-locked VCO uses direct-injection to lock at 2.45GHz with a locking range of 206MHz for a 2.45GHz 250mV incident signal. The chip contains a 128 bits ROM and the data rate is 153Mb/s. The chip designed is using TSMC 0.18 mm 1P6M CMOS process provided by Chip Implementation Center(CIC). The chip area is 479μm × 627μm. The chip works at 1V with 3.82mW power consumption.[[note]]碩
