I do a lot of impedance analysis, creating subcircuits to match
wirebonds from DC up into the GHz range, so my AC skills are still
quite well-honed ;-)
Same here, but you know how it goes. Wet finger in the air, black cat
crosses street, "Oh, need another 3nH here and 4pf over yonder", throw
onto SPICE, find it's really 4nH and 5pF, put that in the design, done.
I have to extract the capacitance from a ref/sense ratio measurement and
through a lossy LC network. No fun. One of our guys had a billiant idea:
Give it to a college kid, let him/her solve it and pay $50 or whatever
is fair for it. But that feels like cheating
