Runtime security code embedded into IoT chip
A lightweight runtime security code embedded into a system-on-chip (SoC) for Internet of Things (IoT) applications. That’s the outcome of a collaboration between MediaTek and Italy-based embedded IoT security firm Exein. EE Times’ Editor-in-Chief…
Ground-fault interruption protection—without a ground?
A friend who was buying an older house was concerned about electrical safety and asked for my opinion as an electrical engineer. All of the AC receptacles (also called outlets) in the house were the two-wire non-grounded type with only a hot…
DeepSeek’s AI stunner and the future of Nvidia
After the release of DeepSeek’s R1, a reasoning LLM that matches the performance of OpenAI’s latest o1 model, trade media is abuzz with speculations about the future of artificial intelligence (AI). Has the AI bubble burst? Is it the end…
1-A, 20-V, PWM-controlled current source
This design idea (DI) takes an unusual path to a power-handling DAC by merging an upside-down LM337 regulator with a simple (just one generic chip) PWM circuit to make a 20-V, 1-A current source. It’s suitable for magnet driving, battery charging,…
Host bus adapter boasts quantum-resistant network encryption
A new host bus adapter (HBA) secures all data moving between servers and storage by facilitating quantum-resistant network encryption and real-time ransomware detection in data centers. Broadcom’s Emulex Secure Fibre Channel HBA encrypts all…
Power Tips #137: Implementing LLC current-mode control on the secondary side with a digital controller
Current-mode control LLC considerations
Inductor-inductor-capacitor (LLC) serial resonant circuits, as shown in Figure 1, can achieve both zero voltage switching on the primary side and zero current switching on the secondary side in order to…
Error assessment and mitigation of an innovative data acquisition front end
The recent design idea (DI) “Negative time-constant and PWM program a versatile ADC front end” disclosed an inventive programmable gain amplifier with integral samples-and-holds. The circuit schematic from the DI appears in Figure 1. Briefly,…
Arm’s Chiplet System Architecture eyes ecosystem sweet spot
Arm has announced the availability of the first public specification drafted around its Chiplet System Architecture (CSA), a set of system partitioning and chiplet connectivity standards harnessed in a design ecosystem supported by over 60 companies.…
The SoC design: What’s next for NoCs?
Today’s high-end system-on-chips (SoCs) rely heavily on sophisticated network-on-chip (NoC) technology to achieve performance and scalability. As the demands of artificial intelligence (AI), high-performance computing (HPC), and other compute-intensive…
