中文摘要 | 本文提出具反向高斯單脈波波形的微微秒脈波整形電路之研究。首先,在脈波整形電路中,運用蕭基特二極體與RC微分電路,組成箝位電路,用以建構單脈波信號。其次,本電路利用微帶線於接面間不遲續的特性,並結合負載電阻,用以建構匹配網路,調整輸出單脈波的反向波形。在分析上,時域與頻域的量測與模擬結果於文中呈頗為一致的實驗結果。在實際量測上,所產生的反向高斯單脈波具有350微蓀秒持續時間,37.03%的波形對成性及7.9%的鈴波位準。此電路可應用於微波通信系統中。 |
英文摘要 | A novel picosecond pulse shaping circuit with inverse Gaussian monocycle waveform is proposed in this paper. Firstly, the pulse shaping circuit utilizes the step recovery diode (SRD, Schottky diode) and RC differentiator to construct the monocycle pulse. Secondly, using the discontinuity in junction and load resistor for establishing the matching networks as well as to decide the inverse shape of pulse. Both simulation and measurement results are with good agreement in time-domain and frequency-domain responses. For UWB applications, an ultra-short inverse Gaussian monocycle pulse with duration 350ps, symmetry 37.03% and related ringing level 7.9% has been obtained. |
