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 ...

Matt Fortin, Applications Engineer at Intersil talks about the active filter designer which is a part of iSim tool. iSim is an interactive web-based tool that allows you to select your supporting ...

A new IC-based approach to EMI filtering in ac-dc power subsystems dramatically cuts inductor size and offers other benefits as well. The nature of the EMI problem in ac-dc supplies and its ...

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 ...

Electromagnetic interference (EMI) due to noise created by switching-topology power devices, even low-power ones, is an ongoing problem. Not only does noise affect its direct circuitry load, but that ...

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 ...

Global Active Filter Market Report 2017 is a professional and in-depth survey on the current state of the Active Filter industry. The report provides a basic overview of the industry including ...
