Circular Spiral Inductor Calculator

The Circular Spiral Inductor Calculator is a tool designed to calculate the inductance of a circular spiral inductor based on the number of turns, spiral separation, inner diameter, and outer diameter. This calculator leverages the formula:

\[ Inductance = \frac{0.03125 \times N^2 \times Do^2}{10^6} \]

where \(N\) is the number of turns, and \(Do\) is the outer diameter in mils. The calculator provides an easy-to-use interface, allowing users to input the parameters and calculate the inductance in millihenries per mil (mH/mil) with precision. This tool is particularly useful for engineers and students working on projects involving RF circuits, where the precise calculation of inductance is crucial for the performance of the circuit.
