Do we really need another design tool for Sallen-Key filters? Aren’t there enough [i] [ii] [iii] [iv] [v] already? Obviously, you and I think that there’s something more to say on this topic, or you ...

My previous column described the Sallen-Key circuit for a low-pass filter. At times, you will not find a low-pass filter with the specifications you need in an anti-alias circuit, so you might decide ...

Low-pass filters (LPFs) are fundamental components in modern electronic systems, serving to permit signals below a designated cutoff frequency while attenuating higher frequencies. Recent advances ...

Editor’s note: This article is a follow-up to the 2011 article, ‘Design second- and third-order Sallen Key filters with one op amp’ on EDN. Author’s Note: The author is revising this article to ...

Binary search, a decrease-and-conquer approach, plays an important role in testing today�s low-pass filters. When testing a low-pass filter, generally you have to use an arbitrary waveform generator ...

A research team from Singapore has successfully designed the world's smallest on-chip low-pass filter which is 1,000 times smaller than existing off-chip filters. A research team from Nanyang ...

Imperfect Amplifiers, Parasitic Capacitance, And Component Selection All Impact Filter Performance At High Frequencies. Since professors R.P. Sallen and E.L. Key described it in 1955, the Sallen-Key ...

This monograph describes the theoretical and practical details of the design of a very linear phase-shift low-pass filter intended to remove noise and other irrelevant information above approximately ...
