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...
In the field of the design of application circuits, a Sallen-Key active low-pass filter is widely employed. Non-inverting amplification is realized, however, the filter is lifted at a far end of a suppression band due to the characteristic of internal resistance of an operation amplifier. The...
