Hi all, I am running an AC simulation (but could be doing also an Sparameter simulation) and I would like to a have an inductor whose value depend on the value of the frequency. And how? Writing an equation L=1/acfreqency does not seem to work for me. Similarly can I access the frequency of the Sparameter simulation? Thanks Fabio |

Hi Fabio, 1) You could use a parameter sweep for the inductance value. Then you would get results depending on 2 variables (frequency and inductance value). Most of the data would be useless, as it has not the frequency-inductance relation, that you want. With a little octave postprocessing you could then extract the data you want. 2) You could write a S-Parameter file (containing the changing inductor) and insert that in your schematic. I guess you would have to calculate the values for the S-Parameter file in a spread sheet, as qucs cannot export touchstone files. 3) Have you looked through the qucs documentation ("Tutorial - Getting Started", "Workbook", "Technical paper") Carsten |
