Can we do .PZ analysis for the circuit that uses inductor with n-port S-parameter

RFStuff

Dear All,

Can we do .PZ analysis for the circuit that uses inductor with n-port S-parameter

Kind Regards,

Parents

  • Assuming you're talking about using the pz analysis in Spectre, then I would say that the results are going to be challenging to interpret. If you use the nport with the default (linear) interpolation method, then it's a frequency dependent component and it will analyse the poles and zeros at a fixed frequency. You could use interp=bbspice on the nport which would give you the poles and zeros of the rational model fitted to the s-parameters, which may be somewhat meaningful.
