I am trying to replicate his wCalc and SPICE simulation calculations for learning purposes.
I've got about everything figured out except how exactly he came to his wCalc results.
Here is a screenshot at my failed attempt of coming to the same result as Oli did using wCalc.
Zo = 177.6Ω L = 642.9 pH/mm C = 0.0465 pF/mm R = 34.46 mΩ/mm Delay = 530.4 ps
Zo = 117.6Ω (considerably off) L = 642.8 pH/mm (only 0.1 ph/mm off) C = 0.0465 pF/mm (same) R = 9.072 mΩ/mm (considerably off) Delay = 530.3 ps (only 0.1 ps off)
Since some numbers, L, C, and Delay are equivalent or off by just a fraction, but Zo and R are considerably off, I'm a bit perplexed.
