Planar spiral coil inductor design

In modern technology, inductors are often shaped in the form of planar spiral coils. At this time, you need a tool help you do inductance calculations. That is, Planar Spiral Coil Inductor Design—Planar spiral air coil, planar inductor, design and calculations based on your requirements. Whatever Octagon spiral coil, Hexagon spiral coil, Square spiral coil, Sircular spiral coil, update in 2020. The thickness of the inductor has only a very small effect on inductance and will therefore be ignored.
