使用電流式主動元件所設計的電路，已經被證明具有較大的頻寬、較大的動態範圍、較大的線性範圍、較小的功率損耗及較簡單的電路結構，因此近來利用如電流傳輸器(CCII)、電流回授放大器(CFA)及運算轉導放大器(OTA)等電流式主動元件來設計電路受到相當的重視。
以往利用CCII所設計出來的振盪器電路，有些電容器沒接地或是利用一個被動元件來控制振盪頻率。在本論文裡，藉由提出一個廣義(可調式)的第二代電流傳輸器(GCCII)來做振盪器；因為可調的電壓增益和電流增益參數可以使得振盪頻率和振盪條件獨立可調，所做出的振盪器電路跟以往的比較有下列優點：(1)電容器完全接地(2)本來不能振盪的電路型態可以振盪(3)直接利用電壓增益和電流增益參數來調整振盪頻率(4)實現之振盪電路就是屬於一種VCO、ICO類型的電路，傳統的VCO、ICO類型電路是非常複雜且不容易設計的，利用此廣義的CCII來設計是很簡單的。
另一方面，還提出一個”使用傳輸參數/反傳輸參數nullator-
norator表示法來完成線性非時變雙埠網路的等效電路”。此電路的提供了滿足線性非時變雙埠網路的傳輸矩陣的等效電路。
對於以上的電路，可用模擬和實驗的方式來驗證電路的正確性，所做出的結果也和理論值相近，確認了電路的可行性。
