1kHz ramp oscillator.

Close the switch to start.
Found this rather interesting circuit on the net. I'm not able to get it to oscillate stably at higher frequencies thought. I think it's because of a glitch in the software. The ramp waveform reaches a peak of -30V when I try to get it to oscillate at higher frequencies, and after a while, the oscillation dies.

Why is the switch in the middle of circuit?!

It won't work otherwise

Every circuit isn't a big fan of oscillators. So i have to do something to get it to work. Try to run the circuit with the switch on and it won't work. open the switch, start the simulation and close it to make it work. This is usually the best way to make such oscillatory circuits run.

If you use the switch on the voltage source, it 'll work just as well i think.

EveryCircuit is a big fan of oscillator. The only kind no simulator likes discontinue oscillators with uncalculateable edges infinte slopes. Anyway, harmonic oscillator are cool in Everycircuit, this type of relaxation oscillator are nothing for any simulator, the fall time is almost infinity small
