The output of the bubba oscillator is a nice sine.

The problem is that i am not able to generate the sinusoidal from the circuit. However when the loopgain remains higher than 1 the amplitude of the oscillation will increase and keep increasing. Email Required, but never shown. For the Bubba oscillator this is the case.

This below is my circuit: The amplitude does not grow any more to infinity. Here’s the output from Oecillator After setting sec as simulation time, the amplitude goes to infinity and at around 51 sec, Derivative of state at time What you see is the oscilator starting. It needs a voltage contolled component which has variable gain, attenuation or resistance.

## Multisim and Ultiboard

You have used ideal opamps I suspect and that means that the amplitude of the oscillation will increase and keep increasing. Sorry, i am quite new at electronics By real op-ampsdo you mean finite gain op-amp?

If you zoom in on the left side you should also see the oscillation but osciolator a much smaller amplitude. This is not a good solution if you need low distortion sinewave. How to achieve a pure sinusoidal waveform from this bubba oscillator And that means the loopgain becomes smaller. The simulation will be stopped. But this will probably result in a distorted sinewave.

The amplitude grows exponentially. It has started to oscillate. Where did i go wrong? And that will result in a stable oscillaror. Sine generator – Bubba Oscillator Ask Question. Zoomed result Simulated for 10sec: Just to add yet another post on this. Better would be to use a tanh x like function so that it limits but in a continous way.

This is the error message. The controller searches the right gain continuously but has proper inertia which prevents the distortion of the sine pulses. Set more time for the simulation. Insert that limiting circuit in parallel with one of the capacitors. So sorry to oscjllator you, i am using MATLAB b, can you upload the file in previous version if thats not much trouble, if not, never mind. Your misconception comes from the fact that you first have to understand the odcillator of operation of oscillators.
