I am confused about 2 different online active filter calculators giving different GBW requirements for the same frequency range. One calculator is giving GBW requirements in the kHz range while the other calculator is saying I need a very high GBW in the MHz range - up to 40 MHz.
I am trying to calculate an 8 pole bandpass filter in the range of 5400 Hz - 7500 Hz and this is what each says about GBW requirement for each section:
first website is https://tools.analog.com/en/filterwizard/:
GBW for each section with the above calculator: 768 kHz, 654 kHz, 741 kHz, 547 kHz
2nd website is https://webench.ti.com/filter-design-tool/filter-type:
