Hey, this is my first post. I am having trouble with the transfer function of this butterworth filter I designed. Any suggestions with helping me get started?

 

Can you go ahead and post what you have been able to do so far?
Maybe all you need is a clue on where you have gone off the track.

You should be able to find the symbolic expression for Vo for the first two stages. Vin should carry through, and when you reach the third stage to find Vo, simply rearrange and find Vo/Vin.

The attached is for giggles.

 

Well I started to do the transfor function for that schematic and it got pretty complicated so I redid the circuit and got a lot simple schematic. Here it is. I am starting the transfer function right now.

 

The attachment did not take.
