Ultra-low-power active filters have received increasing attention in recent years due to emerging applications such as bio-signal sensing and wearable electronic devices, where they are employed in ...

High-performance op amps and specialized software for PCs enable the design of wide-bandwidth active filters, but those advantages don't address the requirements of any specific application. For video ...

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 ...

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 ...

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 ...

The EPCOS PQSine™ series of active harmonic filters from TDK Corp. are designed to optimize power quality. The modular filter systems are designed for 3-phase networks with and without neutral ...

N-path filters exploit periodic switching of capacitors or inductors across multiple parallel paths to achieve high‐quality‐factor, tunable bandpass responses directly at radio frequencies. By ...

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 ...
