The article describes the behavior of Sallen-Key lowpass, antialiasing filter. Although the gain amplitude of most filter in this category continuously decrease beyond the cutoff frequency, it is not the same for Sallen-Key. In fact, it attenuates any signals in the frequency range above the ...

The Sallen-Key (SK) filter is a widely applied topology used to realize a low-pass filter. During the design of the SK filter, the active element is always modeled as an ideal operational amplifier (op amp), however all real op amps have a limited gain-bandwidth (GBW) product. The ...
