本論文利用注入鎖定振盪器，實現頻譜感測器及生理訊號感測器架構。首先由Adler’s equation了解影響鎖定範圍的因素後，將針對放大輸入功率這項條件來增加鎖定範圍。以ADS進行注入鎖定振盪器電路設計的模擬，其量測結果當-17.5 dBm功率注入時，注入鎖定範圍為70 MHz。然後以注入鎖定振盪器實現FM解調器，此晶片所能解調的FSK訊號最低的頻率偏移量及注入功率可達到350 KHz及-39.5 dBm，最高調制速度可達到40 Mbps。接著利用上述設計的晶片進行頻譜感測及生理感測的實驗。首先介紹此架構於頻譜感測及生理感測的理論分析，接著由晶片進行實作，頻譜感測可達到掃瞄速率100 MHz/0.5 ms及最小偵測功率可達到-100 dBm的表現；生理感測在人體距離天線80公分處仍可看到心跳及呼吸活動情形。

This thesis uses injection-locked oscillators to realize spectrum and vital sign sensor. At first, the thesis discusses the factors to affect the locking range based on Adler’s equation, and adopts an increase of injection power to enlarge the locking range. Then, the circuit simulation using ADS is carried out to predict the output response of an injection-locked oscillator. As an implementation result, a CMOS chip of an injection-locked oscillator achieves 70 MHz locking range at -17.5 dBm injection power. In addition, a CMOS FM demodulator is realized with the injection-locked oscillator, showing that the chip can demodulate the FSK signal with a minimum frequency deviation of 350 KHz, a minimum input power of -39.5 dBm, and a maximum data rate of 40 Mbps. With the help of the above CMOS chips, a spectrum sensor and a vital sign sensor are realized. In the test, the spectrum sensor can measure a minimum signal power of -100 dBm at a scan speed of 100 MHz/0.5 ms, while the vital sign sensor can detect the breathing and heartbeat rate at a sensing distance of 80 cm.
