碩士 === 中原大學 === 電子工程研究所 === 90 === In recent years, the current-mode active components is popular in scholastic discussion and commercially used. Current-mode active components have the advantages of wider bandwidths, larger dynamic range, lower power-consumption, smaller area and easier to design. The object of this study is the design analog filter circuit using current-feedback amplifier. This thesis divided into two topics. First, several current-feedback amplifiers to carry out the three-inputs and single-output, second-order universal filter and the single-input and multi-outputs second-order universal filter published in the recent years. I study them in order to find out the skills of designing analog circuits. Second, a voltage-mode four-inputs and single-output second-order universa filter is proposed. The proposed circuit employs only one current-feedback amplifier, two capacitors and three resistors. The use of only one active components simples configuration. PSpice simulation and experimental results of the proposed circuit consist with the theoretical results.
