YesAre you confined to transistors?
The famous function generator, ICL8038, generated triangle waves using something like two constant current sources, one sourcing current 2i all the time and one sinking current i for half of the period. The resulting current to charge a capacitor.Yes
I agree, using opamp is nice, clean and simple. I dont know if you've notice, post #4 is practically 2 discrete opamps
But...
I'm trying to think outside the box, design exercise if you will.
I'm interested in alternative to opamps
I have thought about it too, but then quickly abandoned it because, i hate wasting power.The famous function generator, ICL8038, generated triangle waves using something like two constant current sources, one sourcing current 2i all the time and one sinking current i for half of the period.

Hi,Nothing to do, testing out my various triangle generator designs
Real world non linearity ?!?!

***Edit: I forgot to buffer the output when probing
Could you show some credible data to support this claim?
Sourcing 2x current all the time, is wasting power...one sourcing current 2i all the time
As much as using gasoline with a car to go somewhere.Sourcing 2x current all the time, is wasting power...
Right on! Thanks.Slew rate or bandwidth?
