negative resistance in tranmission line SPICE model
Hi ,
I extrace RLCG using the method propose in "S-Parameter-Based IC Interconnect Transmission Line Characterization"
William R. Eisenstadt, Senior Member, IEEE, and Yungseon Eo
the length of the TL is 500um, in about 60Ghz,the R is come to zero and then to negative. I think negative R is no useful in the SPICE model,What can do ?
And the second quetion is : the R become more and more larger at the beginning ,but why come to small after the largest point ?as show in the picture.How to model this pheonomenon?
Thank in advance!
