Today we are going to explain about one more important concept – “FILTERS”. An electrical filter is a circuit, designed to reject all unwanted frequency components of an electrical signal and allows ...

As a follow-up to my previous blog, Integration Choices: Analog Filters vs. Digital Filters, the next step would be to discuss how to integrate filters into the IC itself. What techniques and ...

A bandpass allows a certain electrical signal to pass while filtering out undesirable frequencies. In a speaker bandpass, the mid-range speaker doesn’t receive tones meant for the tweeter or woofer.

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 ...

The Fraunhofer Institute for Integrated Circuits IIS has developed digitally tunable and reconfigurable RF filters. In a congested spectrum “devices that send and receive data must function reliably”, ...
