The pulse of power: Mastering the PWM relay

Imagine a component that combines the heavy-duty muscle of a power relay with the surgical precision of a digital signal. That is the essence of a pulse width modulation (PWM) relay. While traditional switches are often strictly binary, the…

How Precise Must We Be?

To how many significant digits does Pi (and its peers) remain relevant? Some while ago, I downloaded a file of Pi calculated to one-hundred-thousand digits. A bit later, I downloaded a different file of Pi calculated to one million digits. I…

From AI silicon observability to governed evidence

Artificial intelligence (AI) silicon is increasingly defined not only by compute capability, but by how data moves through the system. Modern AI SoCs, edge AI processors, automotive compute platforms, and AI accelerators depend on large volumes…

5 takeaways from Samsung Foundry’s design tie-up with Synopsys

A fundamentally new approach is required to fuse AI-driven automation and multiphysics intelligence across the entire design and manufacturing flow. That was the crux of the keynote by Synopsys president and CEO Sassine Ghazi at the SAFE Forum…

De-commingling (?) LAN equipment: It’s all in what you call it

A welcome career transition (and employer-responsibility expansion) begs for a hardware-plus-software evolution. Hold his beer; this engineer’s got this. As some of you may have already noticed (assuming you even care about such things), my…

Taming the beast: Memory efficiency in an AI/crypto world

The planet is facing a crisis in energy demand versus supply, and data centers are at the center of this dilemma due to the increasing demand from new data-intensive applications. This article will explore the causes of data center inefficiency…

SiC modules simplify high-voltage topologies

Two 3.3-kV SiC power modules from Wolfspeed target high-voltage energy infrastructure, including AI data centers, renewable energy systems, and grid equipment. The HAB900C33LM4 half-bridge baseplate module supports applications above 800 A,…

AMD enables AI agents with Ryzen platforms

AMD has introduced the Ryzen AI Halo developer platform alongside Ryzen AI Max PRO 400 Series processors to support next-generation agentic AI systems. Both platforms are designed to run AI workloads locally, reducing reliance on cloud infrastructure…

LED controller trims automotive power loss

The MLX81119 RGB LED controller from Melexis integrates a 1-A DC/DC converter to reduce power dissipation in automotive lighting systems. The converter generates an optimized local LED supply voltage programmable from 2.5 V to 6 V. Unlike external…

Automotive bipolar latch boosts magnetic sensitivity

An automotive bipolar Hall-effect latch from Diodes, the AH3711Q provides high magnetic sensitivity with operate and release points of ±10 Gauss. It can be used for brushless DC motor control, rotational speed measurement, linear and incremental…

Entry-level MCUs ease system control

Toshiba is sampling its TXZ+ Entry-Class M4H microcontroller group for small-scale system control of consumer and industrial equipment. Powered by a 120-MHz Arm Cortex-M4 core with an FPU, the devices deliver the real-time performance needed…

A closer look at Huawei’s chip design workaround without EUV

Huawei’s new chip design and how it aims to bypass Moore’s Law amid a lack of access to the latest EUV lithography is now the talk of the tech town. At the heart of this semiconductor breakthrough is 3D stacking—which Huawei calls LogicFolding—alongside…
