What do you really get using a supplier tool for an multiple feedback (MFB) low pass active filter? Let's continue the quest for the best results using the example designs from Part 1. In this online ...

If you're responsible for maintaining quality power at a commercial facility and you've got a problem with harmonics, your best bet is to install a series of active filters. Opting for such filters ...

Today I am experimenting with a single chip Universal Active Filter, in this case I made a small PCB for the UAF-42 from Texas Instruments. I chose this part in particular as it facilitates setting ...

In the last edition of Don’t Fear the Filter, we built up two examples of the simplest and most-used active filter of all time: the two-pole Sallen-Key lowpass. This time, we’re going to put two of ...

Active filters are ubiquitous in electronic design today, performing signal-frequency manipulation and conditioning for audio, IF (intermediate frequency), and digital-signal processing. The success ...

For many analog-to-digital converter (ADC) applications, a simple passive resistor/capacitor (RC) filter at the buffer input will provide adequate antialiasing filtering. However, an active filter is ...
