Several people asked for more information about anti-alias filters used with analog-to-digital converters to remove unwanted signals. This column describes a filter-selection "gotcha," and includes ...

Analog filters play an important part in electronic signal synthesis subsystems, providing functions such as antialiasing and noise filtering for A/D converters (ADCs), as well as “reconstruction” ...

180SMIC_LPF_05 is based on 3rd order Butterworth low-pass filter (LPF) with cut-of frequency adjustment in a wide range. There are 2 modes for cut-off ...

In this article, I’ll describe a few easy steps that will convert any Sallen-Key (SK) or multiple feedback (MFB) active filter from a single-input filter to a summing active filter that gives the same ...

This amplifier-based IC implements dual low-pass filters with matched response at cutoff frequencies up to 10 MHz. To build active filters for high-frequency RF applications, designers may construct ...
