摘要
本文主要介紹了有源濾波器的設(shè)計方法及仿真。此設(shè)計主要分兩部分:逼近和綜合。即先按照給定頻率響應(yīng)特性尋找傳遞函數(shù),再由傳遞函數(shù)求出有源濾波的電路。基本層次是從無源到有源;從低通濾波到高通、帶通和帶阻濾波;從歸一化參數(shù)值到非歸一化參數(shù)值;從理想濾波器到實際可實現(xiàn)電路。有源模擬濾波器是在了解了理想濾波器的模型特性及頻率響應(yīng)特性,濾波器的電路結(jié)構(gòu)及元件參數(shù)和模擬濾波器的頻率變換及元件變換的分析的基礎(chǔ)上設(shè)計出的。

ABSTRACT
The article mainly introduced the active filter design method and the simulation. The design mainly is divided two parts: Approaches and the synthesis. Namely first defers to assigns the frequency-response characteristic to search the transfer function, then extracts the active filter by the transfer function the electric circuit .The basic level is from passive to active; From low pass filter to high pass, band pass and belt anti-filter; From normalized parameter value to non-normalized parameter value; To actually may implement the electricity from the ideal filter. Though the study ideal filters model identity and in the frequency-response characteristic analysis, had understood the filter
