Try Google Fi (Wireless)? The perks-for-the-price are why
Going the MVNO route involves potential risks for cellular companies and their customers alike…but also lots of possible upsides.
In conjunction with my recent deeper re-engagement with EDN from an employment standpoint, I not only reconfigured…
How automation and abstraction are transforming PCB design
Every PCB designer has experienced it. A design progresses through schematic capture and layout only to reveal problems during verification, simulation, design review, or manufacturing preparation. A differential pair violates a critical constraint.…
Battery monitor combines EIS with high cell count
TI’s BQ79826Z-Q1 automotive battery monitor supports up to 26 cells in series and is stackable to 128 devices. Its integrated electrochemical impedance spectroscopy (EIS) engine detects early signs of thermal runaway inside battery cells,…
Smart switch simplifies automotive power sequencing
A smart load switch from Diodes features low on-resistance for reliable power sequencing and rail control in automotive applications. Designated the DML1012ALDSQ, it integrates an N-channel MOSFET with 8-mΩ RDS(ON), minimizing conduction losses…
MCUs optimize control in optical modules
GigaDevice offers the GD32E512 and GD32E252 MCUs purpose-built for high-speed and low-speed optical modules, respectively. The devices target applications in AI data centers, cloud infrastructure, telecommunications networks, and access networks.
The…
GaN inverter board drives compact BLDC motors
EPC’s EPC99132 evaluation board is a GaN-based three-phase inverter for small BLDC motor drives in drones and robotic wrists. The design is built around the EPC33110, a 100-V, 20-A three-phase ePower Stage module that integrates three half…
AV2 decoder joins multi-codec IP family
Allegro DVT’s Pulsar D400 series of multi-format video decoder IP now supports real-time AV2 decoding for advanced SoCs and ASICs. AV2, developed by the Alliance for Open Media, is an open, royalty-free video compression specification designed…
Model your IPs and your NoCs
When chip design and verification teams start a new project, they recognize the need for models that capture the design at a high level of abstraction. However, they tend to focus on acquiring or creating models of the IP blocks used to implement…
4-20mA to 0-20mA converter sips mere microamps
Circuits for converting 4 to 20mA analog current loop signals to 0 to 20mA may be hot topics, but hot implementations of those circuits are not.
Circuit designs for conversion of 4 to 20mA analog current loop signals, which are ubiquitous in…
Metasurface plus photoelectric quantum effect yields sensitive THz detector
I’m always interested in how researchers, scientists, engineers, and manufacturing specialists leverage apparently unrelated advances to their own advantage for devising innovative techniques and advances. This phenomenon is not new, of course;…
Using an oscilloscope’s time, frequency, and statistical measurement domains
Multiple domains provide designers and test engineers with complementary views of acquired signals.
Oscilloscopes originated as instruments that measure electrical signals in the time domain. The advent of the digital oscilloscope, where input…
Neural telemetry: New chip delivers 10x compression while preserving signal integrity
The search for novel ways to treat cognitive, sensory, and motor disorders, and their associated impairments—from restoring movement in people with paralysis, and enabling intuitive control of prosthetic limbs, to re-establishing speech and…
