h0w do I derive a loop filter coefficient to implement design for a 3rd order sigma delta modulator in chain of inetgrator, weighted feed forward summation which has a high pass butterworth NTF with a normalised cut off frequency at 1/16

You could make a cascade of 3rd order and next two 2nd order butterwoth filters. The solution for 2nd and 3rd order filters you can find here:

Dear forum members and experts,
I have some questions regarding the measurement of my taped-out active 3rd order butterworth filter.I am trying to extract the bode diagram of the filter.
I attach a screenshot that contains the schematic of the board (PCB) where the filter is placed.

I am not a RF designer, mostly work with power and digital design. Was curious to make a 3rd order Chebyshev Bandpass (type1) with the help of some software from the web.
I want to use it in the TV VHF band to pass one channel and stop others.
The design parameters are:
Center Frequency: 204 MHz
Pass Band : 6M Hz
Impedance : 75 Ohm

Hey guys. Hope everyone is doing great.
I'm supposed to design a 3rd order butterworth low-pass filter and so I combined 1st order and 2nd order butterworth low-pass. That's what I need to do right? And so I did but there's an error saying "Name "X_U1" is defined more than (...)
