Design

In this article, we establish design guidelines of a spread spectrum modulation circuit as it relates to CISPR 25.

The most common characterization of ground rods actually differs from what is observed in the case of lightning. This article discusses what is observed and how that affects ground rod performance.

This article presents the EMC design techniques for electric vehicle powertrain modules. High voltage EMC regulations for powertrain modules are reviewed first to help understand associated design challenges. The design techniques are then demonstrated in detail to help engineers design a module that will pass the EMC requirements in the test chamber.

Engineers from the Technical University Munich have created a new supercapacitor which is highly efficient and sustainable.

This article discusses the current distribution for the stripline configurations.

The electronic industry has embraced simulation to address several complex design challenges, but reliability is still mostly dealt with best design practices and tested with prototypes. In this article, we present how modeling and simulation approaches can help designers perform virtual prototyping and uncover reliability issues especially EOS/ESD before going for physical prototypes.

How is the proper ESD Protection Cell chosen for a particular design application?

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.

In Part 2 of this two-part article, we’ll discuss the development and use of isolated bonding networks (IBNs).

In Part 1 of this two-part article, we’ll discuss the development of “grounding networks” and the shift to meshed structures to reduce damage from overvoltages. Part 2 will appear in our November 2020 issue.
