The concept of a CFI was validated by the measurement result
on the prototype. The measured inductance and dc resistance
of the fabricated CFI were 1.42 μH and 8 mΩ, respectively.
Due to the limitation of the fabrication process, an inevitable
air gap between the two inductor halves would be introduced
since the solder in the center cannot be ideally flat. Therefore,
the measured inductance (1.42 μH) was 12% smaller than the
