Differential Low-Pass Filter and The Design Formula
Multiple Feedback (MFB) is the best filter topology to use for differential low pass filters. Here’s the circuit diagram: To design this filter, a corner frequency is chosen based on harmonic content desired in the waveform. After that, we have to select a value of capacitor. The value of C1 is equal to C and C2 is equal to 2.67 […]
