Hi
I wish to create a circuit topology that will remove all unwanted frequencies from an input signal, which is created from a phase shift oscillator (if this is possible by implementing something to the oscillator that is even better), to reduce unwanted harmonics as much as possible, I would also like to know if there any topologies that mean the oscillations occur between a certain range Vmin and Vmax

Thanks

Look at mems resonators.

 

What is the frequency?

 

What is the frequency?

1 kHz

Hi Thanks for the suggestion but I would like to create it using conventional analogue components that I can simulate using LTSpice

 

Based on your other two threads on the same topic, I suggest that you reduce or eliminate the harmonics by improving the quality of the oscillator. This will be easier than creating a multi-pole bandpass filter or resonant trap.
