Hi, Bogatin
In your “The power of planes”, you gave an example on loop inductance per area of power planes, which has 2mil dielectric spacing between planes, and you say it is the thinnest dielectric spacing currently in volume production.
My question is wehther 2mil dielectric spacing will lower production efficiency, and increase PCB costs. And is it a common requirement for most PCB providers? For current communication products, more and more processors, DSP, and FPGA or ASICs with low voltage high currents, and multi such devices in a board at the same time, it’s a challenge for power supply design and power integrity analysis.
Now we use 4mil spacing between planes, if we ignore other factors, if we lower spacing we can reduce planes loop inductance based on your simulation results, is it right?

Hello Eric,
I hope all is well with you.
Would you have a pointer to a presentation or diagram showing the difference between the classical and modern 4-port vector network analyzer port numbering? i.e., 1 to 2 and 3 to 4, versus 1 to 3 and 2 to 4 ?
I know I have seen it on your presentations but now that I need it I can not find it anywhere. I tried the web, the Agilent website, and no luck.
I wonder if there is another name for “classical versus modern” port numbering. I know in the Agilent equipment one can specfy this for the s-parameters, but I can not find it.
Thank you.
Raul
