Sallen-Key Filters 💡 Two-Pole & Three-Pole 🌟 Transfer Function & Cutoff Frequency 👉 MANY EXAMPLES!

In this video, we will discuss the Sallen-Key Filters in great detail. These are active filter circuits, having an op-amp or other active component. We will discuss the two-pole and three-pole Sallen-Key filter configurations having a unity-gain and nonunity-gain. We will use the transfer function to determine the expression for the cutoff frequency, low-frequency gain, and high-frequency gain.
Using the Bode plots of each filter configuration, we will also discuss the filter sharpness, low-frequency gain, high-frequency gain, and cutoff frequency. We will workout 6 examples step by step and verify our calculations using simulations in TINA-TI SPICE.
