Understanding phase noise fundamentals

April 8, 2024
This brief technical paper covers phase noise concepts as well as an overview of how phase noise is measured and reported. Learn more about phase noise and its role in oscillators

A stable frequency source is required for electronic and RF devices. Phase noise is the term used to describe measurements of the short-term frequency stability of these sources; a short-term stability or "good phase noise performance" is critical in variety of RF applications, but can be difficult to obtain; with a substantial cost and complexity often associated with even modest increases in phase noise performance. But what are the common effects of phase noise and what is its role in oscillators? Discover them in this paper, which also covers the fundamental concepts & discusses measurement methods.
