I've got a new #KiCad plugin out in the KiCad plugin manager:
KiCoil generates "twisted" planar inductors. You can make it do one- or two-layer spiral inductors, toroid inductors, and many intermediate, hybrid variants in between spiral and toroid inductors.
These hybrid types have wider traces than a single-layer spiral, and have better high-frequency behavior (parasitic capacitance and self-resonant frequency) compared to two-layer spiral inductors. And they look really pretty!
A large grid of 16 layout variants. They look a little bit like flowers, or like spirograph patterns.
Graph of five inductor layouts. The first is a single-layer spiral, the second a two-layer spiral, and starting from the third, multiple spiral arms interleave such that the trace is weaving between top and bottom layer multiple times. Below the layouts, there is a phase diagram visualization of the trace's path.
