An 18 nano-henry inductor seems, to me, to be an impractical inductor
value.
The length of the connecting wires will form an appreciable part of the
inductance. There must be another way of acheiving the desired circuit
functions.

However, to find the length, diameter and number of turns to make such a
small coil you can use program SOLNOID3 which can be downloaded in a few
seconds, free of charge, and run immediately from the the website below.
Try it and see what happens.

Thanks Reg,

I will download that program. It sounded kind of small to me too. I don't
use smd because I don't know how.

The link to the schematic is:
