摘要
同軸電纜在高頻和長距離的資料傳輸中，由於其等效阻抗存在，而使訊號遭受其強度上的損失；此一損失量為訊號頻率的函數。為了彌補此一損失，我們通常利用一等化器將訊號重建增加其可信度。在此論文中，我將以類比電路的觀點，來設計一應用於同軸電纜Belden 8219的等化器，並利用一回授電路，使等化器能針對不同長度的同軸電纜來作補償。考量系統的整合性及低成本，我將使用0.18-μm CMOS 技術，因此在此論文中的電路將以TSMC 0.18-μm CMOS為基礎。

The data transmission of high-speed and long-distance coaxial cable suffers from magnitude losses due to its effective impedance, The loss is a function of signal frequency. To compensate the loss, we use an equalizer to rebuild the signal and increase its reliability. In this work, I would design an equalizer for the application of the Belden 8219 coaxial cable from an analog circuit point of view. It can also compensate various lengths of the cable via the adaptive control loop. Considering the system integration and low-cost requirement, I use 0.18-μm CMOS technology. Therefore, all circuit implementation in this work will base on TSMC 0.18-μm CMOS technology.
