Hi,

I make a simple amplifier circuit using transistor with S parameters file.

Am I right if I tune others elements(resistor...) to find working point of the circuit. Because S parameters file of transistor was calculated in not 0 frequency, but for bias circuit work with O Hz

Other, Can I do automatic optimization in both DC(DC currents, voltage) and AC(Sparameters) at the same time? Genesys seems do not work when I put an ammeter(Current probe) into circuit which using S parameters in optimize.

Any helps!

No one else has this question

In order to perform DC analysis you need to create a lumped element model (also need harmonic balance module). This can be done by fitting the S-parameter data to one of the many transistor models (if its a bjt you need a model for a bjt, or fet model for a fet).. An example of this is in the template file in Genesys. Open "file", then go to "templates", in templates there should be a .wsp file called model extract.
