360 degree Spiral (helix) with tangent end points

Hello,
Id like to create a spiral (starting radius red ring, ending radius purple, with 1 revolution). I would like the end to be tangent/same radius aas the purple circle. Every time i create a helix the end is not tangent to the final radius.
Is this possible? Do i need to make multiple Tangent arc's and smooth?

There is not a default way to do this with the helix feature yet.
You can however, do it with custom features like Parametric Curve by @mahir.
Or here is a default workflow without any custom features at all:
Adjust the start and end tangency of the spline within Sketch - Helix profile. This will control the helix path. In the example, it is set to be tangent for both the OD and the ID.

I like the Parametric Curve approach.
For fun: 3 native features can do it! Adjust the approximation to taste.

Nice! I didn't know we had that tool. 🤯
Curvature is a bit off on that approach though. Not that most even notice good curvature. (Shift + C) for users who don't know that yet.
