Abstract
Sallen-Key active low pass filters (LPFs) have been knows for many years; however, these LPFs generally include passive components (i.e., resistors and capacitors) and active components (i.e., amplifiers) that are within the direct signal path that can contribute to the noise at the output of the filter within the pass band. Here, an LPF (which has the same general behavior as a Sallen-Key LPF) has been provided that AC couples passive components and active components to the direct signal path so as to suppress the noise contribution in the pass band.
