Ever wonder how wide to make the trace when routing from a DCAP to a via or pin?

This paper shows that (for typical circuit boards) traces in the 10 – 20 mils (0.25 – 0.5mm) range have reached the point of diminishing return in lowering inductance: You’ll have to make the trace a great deal wider than this to even get an incremental improvement in inductance.
