SPICE模型提取

對提取模型和原始的數(shù)據(jù)進行對比      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比S參數(shù)來驗證提取模型是否準確，在進行s參數(shù)對比時 對比結(jié)果里有passivated error 和aprox error ，通過他們來判斷spice模型對原始模型的接近程度

請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.
