DAC implementations: The spread-bit PWM strikes back

Taking various considerations into account, the theoretical advantage of the spread bit PWM can be challenging to translate into practice. A recent Design Idea (Reference 1) addressed the implementation of digital-to-analog converters using…

Caliptra-enabled hardware security solution eyes AI SoCs

A production-ready root-of-trust and security orchestration solution provides dedicated hardware-level security for mission-critical data center and AI system-on-chips (SoCs). This enterprise-grade solution also accelerates design deployment…

Radon sensor embeds sizeable alpha particle detector

PIN photodiode collects, counts, and discriminates alpha energies to determine residences’ radon gas-caused cancer danger degrees. Back in late July, when I was working on last month’s published piece on radon gas analysis, I longed to see…

Beyond the port: Fundamentals of passive radiators

When enclosure size and airflow constraints limit traditional bass‑reflex designs, passive radiators offer a smarter path to deep, controlled low‑frequency performance. Audio engineers face a persistent challenge—delivering deep bass extension…

Electron beam energy

Goldilocks and the Three Bears (and their porridge, beds and chairs) have got nothing on this high voltage design challenge. Sometimes a client gets into areas of technology that go way over my head, but I manage to pick up a snippet here or…

You just Inherited a Simulink model you have never seen before. Now what?

As systems grow, the knowledge needed to safely change them becomes harder to retrieve quickly, even when the design itself is sound. Models increasingly encode not just algorithms, but also assumptions, trade-offs, and system-level intent that…

Debugging intermittent Comcast, part 4: Broadband diagnostics

There’s a lot you can potentially do to boost your WAN’s downstream and upload speeds, as well as to minimize its latency. But only if your service provider lets you. This is my final post in this series. Really. I promise! Like I’ve said…

The Microsoft-reminiscent iPhone Duo: How much customer holding-and-folding is necessary to keep Apple from folding on the experiment?

New smart phones, earbuds and watches, this year with an added dash of memory price increases. It’s September in Cupertino again. September 1 was Tim Cook’s last day as Apple’s CEO, after a 15-year tenure with that title. Hereafter he’ll…

Altera brings quantum-resistant security to FPGAs

Altera now provides post-quantum cryptography (PQC) support for Agilex 3 and Agilex 5 FPGAs, helping strengthen system security. The FPGAs’ reprogrammable architecture enables designs to evolve as new threats emerge and security requirements…

AOS boosts power density with 600-V MOSFETs

Two 600-V MOSFETs from AOS come in top-side-cooled packages with co-optimized electrical and thermal paths to maximize power density. The AOGT037V60DE2 and AOGT060V60DE2 αMOS E2 Super Junction MOSFETs feature a built-in fast body diode for…

Dual-port MIPI D-PHY SerDes delivers 20-Gbps bandwidth

A SerDes chipset from EverProX, under its Silicon Line brand, aggregates two simultaneous MIPI D-PHY camera streams, each at up to 10 Gbps, over serialized links. As the first entry in the Silicon Line MIPI Serial Data Link (MSDL) family, the…

Marelli, Microchip extend ASA-ML to displays

Marelli and Microchip have announced a display connectivity solution that uses the open-standard ASA Motion Link (ASA-ML) to stream graphics and video from a vehicle’s central computer directly to automotive displays. The companies say the…
