I am using a 555 timer to produce a square and triangle wave with a symmetric current source although what I simulate in Lt Spice isn't really transferring into real life. The problem gets worse at higher frequencies around 30khz and improves a bit at around the 5khz range. Is there any way to modify this circuit to produce a clean output in the 30-200khz range?
I've attached what I get on my scope compared to LT Spice.
