Function to synthesize the physical parameters of a single layer, uniformly spaced, air core, solenoid inductor. The physical dimensions of the coil are synthesized from an inductance specification.
// we want 220 nH
L=220e-9;
// we'll synthesize the number of turns
N=0;
// we'll synthesize the length/fill
len=0;
// we'll synthesize the length/fill
fill=0;
// wire size
AWG=22;
// Resistivity of copper (ohm-m)
rho=1.72e-8;
// 0.25 inches inside diameter
dia=0.25*0.0254;
// 10 MHz operation
f=10e6;
// synthesize for minimum number of turns
flag=0;
