Editor’s note: My good friend and long-time colleague, Michael Steffes, expands upon my introduction article, Rauch filter basics, and adds some very useful and practical insights into the Rauch ...

A number of years ago, I posted an article and spreadsheet on EDN that enables the design of 2 nd and 3 rd order Sallen-Key low pass filters given the poles of their filter characteristics. The user ...

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 ...

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 LT6600-10 combines a high-speed differential amplifier and a 10-MHz low-pass filter. Gain is programmed with two resistors for a gain range of −12 to 12 dB. It also provides the necessary level ...
