碩士 === 中原大學 === 電子工程研究所 === 91 === 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.
