摘 要
近年來，電流式電路電路已被證實具有較高的頻寬、較大的動態範圍、較好的線性、較簡單的電路結構與較低的功率消耗。在適應性類比信號處理中，濾波器的可調性在許多情況下是相當有用的。
因此，本篇論文將討論以下的主題:
1. 以互補式金氧半電晶體(CMOS)實現廣義第二代電流傳輸器(The Generalized Second Generation Current Conveyor: GCCII):利用由上而下的設計法，吾人將類比電流乘法器、類比電壓乘法器與第二代電流傳輸器組合成廣義第二代電流傳輸器，其電壓增益與電流增益可由外部的控制電壓與控制電流來調整，與第二代電流傳輸器比較，廣義第二代電流傳輸器在實現電路系統函數時提供了兩個可經由電子方式調整的自由度。
2. 二階萬用濾波器設計: 吾人提出兩個新型的萬用濾波器，其諧振頻率、品質因數與增益皆為可調，這兩個濾波器具有以下的優點: (1) 主動元件與被動元件的靈敏度很小。 (2)所有電容均接地，電路適合積體化。 (3)諧振頻率ωo、品質因數Q與輸出增益皆為獨立可調。 (4) 不需要匹配條件。 (5)相同電路組態提供低通、代通、高通、帶拒與全通等五種濾波功能。
以LM13600、AD844與可變電阻進行實驗量測，同時以CMOS
廣義第二代電流傳輸器做HSPICE模擬，兩者結果都顯示與理
論值非常接近。
3. 使用HSPICE極零點分析來判定具有實際主動元件的線性非時變主動電路是否穩定。以電壓控制電壓源(E)與電流控制電流源(F)建構理想廣義第二代電流傳輸器的等效電路模型，這理想模型將有助於吾人在設計大型系統時，減少模擬時間並且增加設計效率
。
