摘要

本論文中，使用第二代正型電流傳輸器(CCII+)合成轉阻放大器(transresistance amplifier ;TRA)實現HKN(Kerwin-Huelsman-Newcomb)濾波器，並且利用HSPICE去模擬驗證，本文中所使用的TRA是由三個正型之第二代電流傳輸器及一個電阻器所組成，利用此元件所設計之電路適合於操作在高頻及積體化。
本文章提出利用TRA來合成高階濾波器，我們可以發現在電路往高階發展時，可預測其電路及轉移函數的規律性，我們利用信號流程圖去設計濾波器電路，利用梅森增益公式(Mason’s gain formula)，理論計算和模擬實驗將相互驗證其正確性。

In this thesis, the Kerwin-Huelsman-Newcomb (KHN) filter employing transresistance amplifiers (TRA) based on the second -generation current conveyors (CCII+) is proposed and its simulation results using HSPICE are demonstrated. The TRA is composed of three positive-type second-generation current conveyors (CCII+) and a resistor, It is suitable for high frequency and IC implementation.
A high-order filter employing such TRA is presented, we found not only the structure of them will be regular, but also the transfer function. Both structure and transfer function will be predictable when they are developed as high-order filter. In order to find out the characteristics of this circuit, the signal flow graph is often adopted. Also, the rule of Mason’s gain formula applied to signal flow graph is introduced. In the thesis, simulation results that consist with the theoretical analysis are obtained.
