Welcome to the Active Filter series. This video, is about the Sallen-Key active filter topology. We will derive a generalized transfer function, and then derive all equations, for the low-pass configuration. In an upcoming video, I will lay out a methodology, for selecting the resistors and capacitors, that I discovered, and consider to be a solid approach. There are a lot of papers and videos, that cover this topic, but they all seem to have many algebraic steps left out.
