With CCS and a Comparator, all on a single rail 10V power supply...

Maybe I am missing something here. I don't see a triangle wave. What voltage amplitude does it have.

Shake your phone, it'll need noise to kick start.

I held my phone in the sun, pointing north at noon and then I saw the tringle wave, first on the horizon, then on my phone.

Ok!!! Edited the circuit, added a switch to start oscillation.

Awesome! How did you get it to work?

The problem was in the current sources, the can charge or discharge the cap linearly without a problem. But if the cap voltage gets too close to 10v or 0v, it'll force the transistort to their non-linear region. Which seems to cause the problem... so if you set the hysterisys of the comparator well clear off 0V and 10V you'll be good to go...

Here the hysterisys is between 3V and 6V

Between 2 and 6v
