Often, low voltage signaling issues are silent during the initial evaluation phase of product development, and once the power is turned up suddenly, communication stops being reliable. By identifying key analysis steps at each stage of the design process, this two-part article will help you plan, identify, and solve these issues.

Electromagnetic interference (EMI) and excessive heat pose considerable risk to the proper operation of electronic systems within commercial and defense drone technology. By implementing solutions such as EMI shielding products and thermal interface materials, engineers and product designers can mitigate risks and meet regulatory requirements needed for high reliability and performance.

This series of articles delves into the design principles of power filters for switched-mode power converters and similar applications, focusing on conducted and radiated emissions. Part 1 provides an overview of filter design principles, emphasizing the need for specialized approaches to meet EMC specifications in an increasingly electrified and sustainable world.

A Charged Device Model (CDM) simulation method has been demonstrated to predict CDM fail current of receiving circuits with gate oxide connected to pad. This method involves inclusion of 20ps rise time edge into the stimulus. It was shown previously that this fast rise time component of the pulse can cause the gate oxide damage. The simulation method is intended as a schematic-level tool during pre-silicon design phase to deliver CDM ESD protection. Simulation results are verified by silicon results with qualification CDM test on package and Transmission-Line-Pulse (TLP) measurements on wafer-level.

This article provides an overview of high-altitude electromagnetic pulses and the damaging effects they pose to sensitive electronic circuitry, equipment and systems that support a wide range of critical applications, along with common EMP protection approaches and current testing methods used to evaluate the resilience of equipment and systems exposed to an EMP attack.

Designing safe products powered by lithium-ion batteries requires an understanding of how the battery pack will behave while undergoing thermal runaway. In this work, fractional thermal runaway calorimetry is used to estimate the energy release from cells at different states of charge when undergoing a thermal runaway.

Keysight Technologies, Inc. introduces RFPro Circuit, a next-generation radio frequency (RF) simulation tool targeting the complex, multi-physics requirements of today's RF integrated circuit (RFIC) designers.

In today’s ever-changing world, nothing ever stays the same! That trend reportedly extends even to the tenets of Fourier’s Law, a 200-year-old science-based principle that defines how heat diffuses through solid materials.

The trend of progressively migrating both ESD and EMC immunity from the system/board to the component level is creating unprecedented challenges for the component ESD designer.

The narrow ESD design window in current FinFET technologies creates a special challenge for the robust ESD design of high-speed interfaces. Smart circuit-ESD co-design can help achieve the required ESD robustness without deteriorating functional performance.
