Hi:

Do someone know a formula for the self-capacitance of a flat
spiral coil (as the ones used as primary coils)?
Considering a coil as a coiled transmission line, I can obtain
an equivalent self-capacitance that will be close to the actual
value, but I would like to have other expression (or experimental
measurements) for comparison.

Thanks,
