Hi
I am trying to create a Phase Shift Oscillator with a frequency of 5kHz, which I have done now (using a 3 stage RC ladder network and an inverting operation amplifier (with gain of 29)).
To improve this design I would like to remove unwanted frequencies from this circuit, which are visible when viewing a FFT (fast fourier transform) any tips/guidance/circuit topologies in order to add to this oscillator would be much appreciated .
I personally would also love to know how could I adjust the oscillation so that it occurred between two voltage this more out of curiosity, is there some topology I can add to allow this?
Thanks
