Transmission Line Reflections at the RL and RC Loads

This article discusses the reflections on a transmission line terminated with either an RL or an RC load.

PCB Return-Current Distribution in the Stripline Configurations

This article discusses the current distribution for the stripline configurations.

PCB Return-Current Distribution in a Microstrip Line

This article discusses the distribution of a PCB return current underneath top trace for the microstrip configuration. Next month’s article will discuss the distribution for the stripline configurations.

Measuring Differential- and Common-Mode Current Radiation from Cables

This article discusses the common-mode and differential-mode radiation from cables and presents the measurement results from the SMPS connecting wires.

Principles of Switched-Mode Power Supply Design for EMC Performance

This article discusses the basics of a step-down (buck) DC Switched-Mode Power Supply (SMPS). It should serve at an entry-level tutorial and a building step towards the more advanced designs.
