In this situation, the Sallen-Key active filter can save the day. This circuit implements a 2-pole filter. Cascading several stages can give you a steep attenuation curve with a very sharp knee. LOW-PASS FILTER DESIGN Although there are many filter types and ways to implement them, here’s...

I was designing a needed low pass filter in Sallen-Key configuration and everything goes as normal. Casually look at the Chapter 8 - Analogue Filters by AD, a few reports from TI and follow the procedures. But suddenly, I've got a QUESTION: does the order of resistors matter in Sallen...
Techniques have been presented for the design and comparative analyses of second and third order Sallen-Key low pass filter sections having single op amp topologies with arbitrary DC gains. Means of determining the stability of each design for specified component tolerance variations have been derived...
