I have been working on some op amp oscillators lately and really struggling with the sine. I had a wien bridge running but I want to control frequency with one dual ganged pot (or just a single pot, if possible). Can this be achieved by simply putting another integrator on a triangle oscillator and connecting the output to the negative input of the schmitt trigger? It works in this simulator applet but not on my breadboard, although I'm using tl082's so not a big surprise.
Any suggestions on how to make this work i.e. opamps, virtual grounds, different circuits altogether?
I've also got 741's, 324's, npn's, and pnp's.
