Gearing Up For Next-Gen Power Semis


After years in R&D, several vendors are moving closer to shipping power semiconductors and other products based on next-generation wide-bandgap technologies. These devices leverage the properties of new materials, such as aluminum nitride, diamond, and gallium oxide, and they are also utilized in different structures, such as vertical gallium-nitride power devices. But while many of thes... » read more

Will The Fitbit Charge 5 Outshine The Fitbit Luxe?


We don’t know, and we do not comment on whether one device is better than its previous generation. What we do is look at and compare generations of devices. And while we wait for our pre-order of our Fitbit Charge 5 to arrive, we will take a look at what Fitbit Luxe has inside of it. Fig. 1: Fitbit Luxe. Fig. 2: Fitbit Inspire 2. The Luxe has other changes from the Inspire 2, inc... » read more

Short-Circuit Ruggedness In SiC MOSFETs


Trench-based silicon carbide power MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors) represent a dramatic improvement in the Figure of Merit (FOM) values of power conversion switching devices. As a result, outstanding system performance is achieved, enabling higher efficiency, power density, and reduced system cost for many applications. Today, for major target applications for S... » read more

Gallium Nitride — Gate Drive Solutions For CoolGaN 600V HEMTs


This paper explains the gate drive requirements for Infineon’s CoolGaN 600 V e-mode HEMTs. Various driving solutions are discussed, ranging from the standard RC-coupled driver to a new differential drive concept utilizing dedicated gate driver ICs. In half-bridge topologies, a hybrid configuration combining isolated and non-isolated drivers could be an exciting alternative. Practical applicat... » read more

The Battle For Post-Quantum Security Will Be Won By Agility


By Thomas Poeppelmann and Martin Schlaeffer Due to their special features, quantum computers have the disruptive potential to replace existing conventional computers in many applications. They could, for example, calculate simulations of complex molecules for the chemical and pharmaceutical industry, perform complicated optimizations for the automotive and aviation industry, or create new fi... » read more

Will Automotive Ethernet Win?


As internal combustion engines are replaced by electric motors, and mechanical linkages increasingly replaced by electronic messaging, an in-vehicle network is needed to facilitate communication. Ethernet, amended for automotive and other time-sensitive applications, appears to be the network of choice. But is that choice a done deal? And will Ethernet replace all other in-car networks? The ... » read more

Grappling With Smart City Security Issues


Security concerns are rising as cities seek to modernize services by connecting them to the internet and to each other, creating a widening attack surface that is a potential target for everything from disruption of services to ransomware demands. The goal of smart cities is to apply technology and intelligence to a variety of services to enable independent operation, real-time response, as ... » read more

Why TinyML Is Such A Big Deal


While machine-learning (ML) development activity most visibly focuses on high-power solutions in the cloud or medium-powered solutions at the edge, there is another collection of activity aimed at implementing machine learning on severely resource-constrained systems. Known as TinyML, it’s both a concept and an organization — and it has acquired significant momentum over the last year or... » read more
