臺灣博碩士論文加值系統

本論文係使用TSMC 0.18 μmCMOS 製程研製兩型應用於5.8GHz 非接觸式生理訊號雷達感測晶片，一型雷達感測晶片不包含低雜訊放大器，另一型則將雷達系統整合於單一晶片中，且該晶片包含被動式雙平衡混頻器、線性功率放大器、低雜訊放大器、壓控振盪器，及射頻被動電路等關鍵零組件。此外，為克服雷達偵測零點問題，本論文採用直接正交轉換電路架構實現雷達感測晶片。
本論文之晶片使用鎊線封裝於印刷電路板上，透過連接收發射天線與基頻放大器，於成人受測者前50 公分處進行量測驗證，所測得之每分鐘心跳次數與市售醫療及血氧濃度計量測結果吻合，驗證雷達系統之有效性。

This thesis presents two types of 5.8-GHz radar sensor chips for non-contact
vital sign detection. The sensor chip is designed and fabricated in TSMC
0.18 μmCMOS 1P6M process. In order to overcome the null-point detection, the
system configuration of the quadrature direct conversion is adopted to implement this radar chip. The first radar chip does not include an on-chip low-noise amplifier. For the second radar chip, all the active and passive components of the radar system are fully integrated in a single CMOS chip. With packaging on the printed-circuit board and connecting transmitting and receiving antennas, two radar sensor chips have been successfully demonstrated to detect the respiration and heart beat rates of a human
adult at about 50 cm measurement range. The measured heartbeats per minute are in a good agreement with the results acquired by the finger pulse oximeter. The measured results in this thesis demonstrate the effectiveness of the developed radar chips.
