Trace Analyzer Benchmark of Couled Striplines

NEW! Download the feature-rich application version of the trace analyzer.

The parameters for the stripline are given below:

  • w = 11.7 um
  • s = 6.4 um
  • b = 25.4 um
  • t = 1.4 um
  • er = 3.25

Characteristic impedance values computed by FlexPDE, a finite element (FEM) tool, and LINPAR, a method of moment (MOM) tool, are listed below:

Method

Zodd (ohm)

Zeven (ohm)

FlexPDE

41.05

60.56

*LINPAR

40.82

59.75

Trace Analyzer

40.94

60.40

* NOTE: Since Trace Analyzer applet only evaluate the lossless parameters, LINPAR is configured to report only the L/C matrices in order to have to fair comparison.

A specialized version of Trace Analyzer is shown below. User can verify the result by using menu Calculate::Impedance and use it as a template to solve similar problems.
