This is not a standard way of drawing, we can only guess.

I guess it's a MOS tube. But the arrow is pointing outwards, so it's hard to tell if it's a P-channel tube or an N-channel tube. The standard way of drawing is that the arrow is pointing outwards, so it's a P-channel tube. But this is not the standard way of drawing, so it's hard to tell.

Looks like a schematic diagram

Since it is a reference circuit, it should be made by professionals.

Can you post a screenshot of the segment?
