Concepts of switching regulator EMI and noise mitigation
This section discusses EMI, noise and ripple with a more conceptual approach to serve as a primer for the rest of the series.
Before we dive into specific application-based examples of noise and EMI mitigation, let's start with the basics. What is noise? What is EMI? What is ripple? How are they measured? What are some common approaches to limiting their effects? This section discusses these topics with a more conceptual approach to serve as a primer for the rest of the series.
