SUMMARY

The discussion centers on analyzing circuits using z, y, s, and abcd parameters, particularly in the context of microwave engineering. Users seek software tools to compute these parameters efficiently. Sandy mentions the .NET statement in SPICE as a potential solution, although they have not personally used it. Additionally, LTSPICE is recommended as a suitable application for this analysis.

PREREQUISITES
  • Understanding of circuit analysis concepts, specifically z, y, s, and abcd parameters.
  • Familiarity with SPICE simulation software.
  • Basic knowledge of microwave engineering principles.
  • Experience with .NET programming for advanced SPICE usage.
NEXT STEPS
  • Research how to implement the .NET statement in SPICE for parameter calculations.
  • Explore LTSPICE features for circuit analysis and parameter extraction.
  • Study the mathematical relationships between z, y, s, and abcd parameters.
  • Investigate additional circuit simulation tools that support microwave analysis.
USEFUL FOR

Electrical engineers, microwave engineers, and students in electronics courses who are focused on circuit analysis and parameter computation.

Hey all,

Is there some sort of program that allows one to analyze circuits in terms of z, y, s, and abcd paramaters? A lot of my microwave course revolves around analysis in this fashion, and I want to ensure that I am determining the correct paramaters for a given set up.

As an example, in the image we have a transistor with a resistor. The transistor (alone) has the impedance matrix shown in the image. Is there a program that can tell me the z, y, s, abcd parameters of the circuit as an entirety? I can do it by hand, but I'd like to check my answers.

Thanks in advance,

sandy

Yes, the .NET statement in SPICE will compute all of that. I confess I have never used the .NET statement...
If you need a SPICE app, google "LTSPICE".
