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 ...

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 ...

An easy way to conceptualize active filters is thinking about audio speakers. A speaker crossover has a low-pass, high-pass and band-pass effect breaking a signal into three components based upon ...

Almost all efforts immediately constrain implementations by unity gain in the op amp, equal R or equal C, or both. When multi-stage filters are implemented with gain, most of the gain is placed in the ...

The design of analog active filters has evolved from manual component selection to sophisticated optimisation frameworks. Classic topologies—Bessel, Butterworth, Chebyshev and elliptic—provide ...

The IEEE's Applied Power Electronics Conference (APEC) is a must-go event for designers who need to keep up with the latest power-related technologies, products, and design practices. So, it's no ...

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 ...
