Validate idial inductor using Yparam expression

Hello , i would like to verify an idial inductor using its Y-param.i have built a two port system as shown bellow and performed SP simulation for it.

From the direct plot window there are only option to view the Imaginary or the Real part of the Yparam where as in my formula i need the whole Complex number(as shown bellow).

When i imported the imaginary part it showed me imag(ypm('sp 1 1)).

I assumed ypm('sp 1 1) is Y11. so by this logic my formula need to be expressed as

(ypm('sp 1 1)+ypm('sp 2 2)+2*ypm('sp 2 1))/(ypm('sp 1 1)*ypm('sp 2 2)-ypm('sp 1 2)*ypm('sp 1 2)).

Afterwards i pressesed the button of "evaluate the buffer and express the result in a table" i got the table shown in the end.
The table has only real values, no complex numbers in it .

Where did i go wrong?
Thanks

Hello Andrew i have tried to implement the expression you developed by creating each expreesion individually and plotting the last one as shown bellow.

When i tried to plot the expression as shown in the end , i didnt get any error in the Log(attached).
where did i go wrong plotting the final expression?
Thanks

You wouldn't get an error in the spectre.out file because these expressions are not evaluated by the simulator - they're evaluated by ADE. So not sure why you posted the simulator log file.

Something got mangled when I posted the expression and you have it similarly mangled. The first expression should be:

(spm('sp 1 1) - ((spm('sp 1 2) * spm('sp 2 1)) / (1 + spm('sp 2 2))))

and not

(spm('sp 1 1) - ((spm('sp 1 2) * spm('sp 21)) / (1 + spm('sp 2 2))))

There's a missing space between the 2 and the 1 in the third spm call. When I do this incorrectly, I get errors in the CIW including:

*Error* ("spm" 0 t nil ("*Error* spm: too few arguments (at least 3 expected, 2 given)" (sp 21)))

ERROR (ADE-1057): Could not evaluate expression
Name:'s11_1port'
Expression:'(spm('sp 1 1) - ((spm('sp 1 2) * (spm 'sp 21)) / (1 + spm('sp 2 2))))'
because of the following error(s)
("spm" 0 t nil ("*Error* spm: too few arguments (at least 3 expected, 2 given)" (sp 21)))
Ensure that the definition of the expression is correct.

So that's pretty clear. There are subsequent errors because the next expressions fail due to s11_1port not evaluating.

If you correct the expression to have the space between the 2 and the 1, it then works fine and L is plotted.

Regards,

Andrew.

Hi yefj,

For some reason, my previous post is not included. I am trying to include it again.

Hi yefj,

In addition to Andrew's comments regarding your subsequent computations, I still believe you have a sign error. As validation, I made a Virtuoso schematic with your two ports and an ideal 1 nH inductor. I performed an S-parameter analysis and exported the real and imaginary parts of the y parameters. I converted the y parameters to z parameters and computed the imaginary part of the input impedance using the 50 ohm load port. The plot of the imaginary impedance is shown below and it is exactly as desired with a positive complex value of 62.3 ohms at 10 GHz. I have also attached the Excel file I used to do the conversions and create the plot. A screenshot of the schematic I used is also contained in the Excel file.

Hi Shawn,

Thanks for re-posting, although it is actually there - here's the link: https://community.cadence.com/cadence_technology_forums/f/rf-design/41676/validate-idial-inductor-using-yparam-expression/1360601#1360601

What seems to happen is that the forums collapse some of the posts (especially when there are very long posts with a gazillion images such as yefJ tends to post) and so sometimes they are hard to find again (I have reported this a while back - the workaround is to take the URL of the thread and remove the trailing part (the bit after yparam-expression/ in the URL) and then you can re-access everything).
