    Back to Basics: Impedance Matching

    June 5, 2020
    Impedance matching is easy if you know the basics.

    This article series is in the Analog topic within our Series Library.

    The term “impedance matching” is rather straightforward. It’s simply defined as the process of making one impedance look like another. Frequently, it becomes necessary to match a load impedance to the source or internal impedance of a driving source. A wide variety of components and circuits can be used for impedance matching. This series summarizes the most common impedance-matching techniques.
