The output of the bubba oscillator is a nice sine.

Here’s a circuit that should actually work, using a quad LT and a single power supply rail: Insert that limiting circuit in parallel with one of the capacitors.

Trevor Yeah, strangely enough this oscillator relies on the non-ideal properties of the opamps. The problem is that i am not able to generate the sinusoidal from the circuit.

These opamps cannot generate infinite voltages so at some voltage their output voltage will be less than what you would ideally bybba.

That’s what your plot shows. But this will probably result in a distorted sinewave.

## Multisim and Ultiboard

How to achieve a pure sinusoidal waveform from this bubba osdillator Just to add yet another post on this. The amplitude does not grow any more to infinity. This is what is causing an exception And this below is my result Simulated for 10sec: Take a couple of zener diodes connected in series having the anodes against each other.

For the Bubba oscillator this is the case. I suggest reading about the Barkhausen stability criterion. The only property which is important is an amplitude limitation due to the power supply rails.

Email Required, but never shown. A drastic improvement reduction of distortion is possible when we use two different supply rail voltage pairs and bkbba the ouput is taken from the block with the larger supply voltage limiting effect in the block with smaller supply voltages.

So sorry to bug you, i am using MATLAB b, can you upload the file gubba previous version if thats not much trouble, if not, never mind. And that means the loopgain becomes smaller.
