s parameter help!!

i want to design an oscillator with BJT.
how can i transform the common emmiter s parameter
to common collect in ADS,ANSOFT?

This site is about S-Parameter...maybe you this could help you! :D

The adlab two port program available here for a 20 day trial http://home.t-online.de/home/weberconnect/esoftw2.htm will convert between different parameter sets and common element.

In ADS a two port S-parameter (S2P file data item) is always depicted as a three port one and the common emitter S-parameter is internally converted to a three port network ; you can the use the same data item in common collector mode also without having to convert it externally (If you have the model of the BJT in ADS then you have to generate the S-parameter file )
