對(duì)提取模型和原始的數(shù)據(jù)進(jìn)行對(duì)比 passivated error 和aprox error 分別是什么意思，謝謝
講得不清不楚，沒有建議。
spice模型和原始模型分別仿真對(duì)比S參數(shù)來驗(yàn)證提取模型是否準(zhǔn)確，在進(jìn)行s參數(shù)對(duì)比時(shí) 對(duì)比結(jié)果里有passivated error 和aprox error ，通過他們來判斷spice模型對(duì)原始模型的接近程度
請(qǐng)善用軟件的幫助文件。
CST MWS幫助文件《Network Parameter Extraction Overview》：
Approx. Error of S: Shows the relative approximation error over the frequency.
Passivated Error of S: The error of the passivated S-parameters over the frequency.
PS: Furthermore, the passivity requirements are met which means that the equivalent SPICE circuit is stable and passive and therefore ideally suited for embedding in larger systems or circuit simulations.
