為了解決有源模擬濾波器傳遞特性函數(shù)設(shè)計中手工計算方法復(fù)雜、時間長，查表法精度不高的問題，提出了一種快速協(xié)同設(shè)計方法，該方法先通過在MATLAB環(huán)境下將基于頻率變換的有源模擬濾波器傳遞函數(shù)設(shè)計方法程序化，之后只需給出濾波器電壓衰減設(shè)計指標(biāo)和邊界頻率即可快速獲得濾波器傳遞函數(shù)或其二階級聯(lián)傳遞函數(shù)中各多項式的系數(shù)并在此基礎(chǔ)上進(jìn)行電路綜合，大大縮短了設(shè)計時間，最后通過EDA工具Pspice對其綜合的電路進(jìn)行性能指標(biāo)的仿真，進(jìn)一步驗證和完善設(shè)計方案，為電路實現(xiàn)的可行性提供了可靠的保障。仿真實驗結(jié)果表明協(xié)同設(shè)計方法快速、直觀、準(zhǔn)確，大大提高了設(shè)計效率，對有源模擬濾波器特別是高階濾波器的設(shè)計具有很好的實際指導(dǎo)意義。

　　Abstract:

　　In order to solve the problems in the design of transfer function for active analog filter， such as long time and tedious manual calculation and low precision table look-up， a kind of rapid collaborative design method for active analog filter is proposed. First， transfer function design based on frequency transform is programmed in MATLAB， then coefficients of transfer function or second order cascade transfer function are given rapidly according to the voltage attenuation index and edge frequency based on MATLAB program. With the above results， it can greatly shorten the time of circuit synthesis. Finally，the filter circuit performance simulation is presented through EDA/Pspice，which furtherly verifies and improves the design. All of these provide a reliable guarantee to the feasibility of circuit realization. The simulation results show that the collaborative design method is fast，intuitionistic and accurate， it also enhances the design efficiency greatly. This method plays a practical introductive significance on active analog filter?蒺s design especially for high order filter design.
