The result will be some kind of oscillator, but it is uncommon.
I updated the post with a modified schematic, that way would be equivalent? DimitriPetrucci see the update. I’m trying to understand what’s the purpose of the two lm3011an connected to the compensation pin 8and what the output of the comparator is supposed to be. The behaviour of the diode voltage limiter is similar to this circuit:.

This will have effect on the load you can attach to this circuit. But, what if I put a capacitor in the positive feedback?
See how the signal is cut. As long as the OpAmp works in a open feedback loop as a comparator no feedback connection, maximum gain both will output similar waveforms. Todor Simeonov 1, 3 Similar thing is done on Fig. The second schematic is not equal to the first. The second will work with minimal distortion only with highest impedance inputs – about 1 MegaOhm, while the first can work with kOhm loads without an issue. Email Required, but never shown.

Post as a guest Name. The first makes voltage limiting on the low power circuit of the OpAmp and then the ouput emitter follower as its name says outputs a voltage with similar waveform but with higher load capability.
Update The second schematic is not equal to the first. Without a datasheet, this is a non-question. The difference will apper when you close the feedback loop for some exact gain.
