Calculating An R-C Snubber Blog 4/26/2016 4 comments Most power supply designers have encountered ringing in switch-mode converters. This ringing can generate radiated and conducted noise, cause circuit jitter, over-stress components, and create excessive dissipation. This is often a major concern in applications such as audio, processor power, and any design that requires electromagnetic interference (EMI) qualification.
NI's mmW Radio Speeds 5G Research News & Analysis 4/21/2016 1 comment National Instruments announced a software defined radio for the millimeter wave spectrum. The transceiver system that can transmit and/or receive wide-bandwidth signals at 2 GHz real-time bandwidth, covering the 71-76 GHz spectrum. The system comes with accompanying software.
EDA Group Broadens Mission News & Analysis 3/31/2016 10 comments The EDA Consortium renamed itself the Electronic System Design Alliance, taking on a broader role including semiconductor IP, embedded software and advanced packaging.
VR Not Ready for Standards News & Analysis 3/17/2016 2 comments Virtual reality may have been big enough to get its own sub-track at Game Developers Conference and require a last-minute move to a set of larger rooms. But VR hasn’t developed enough to create standards.
5G mmW Models Go Open Source News & Analysis 3/11/2016 Post a comment In an effort to speed 5G development, NYU Wireless will provide its
channel models and measurements for cellular propagation in the millimeter wave (mmW) band as free, open source software. The simulation will help product developers understand the behavior and capabilities of the mmW radio spectrum.
Engineering Bloopers at DesignCon 2016 Blog 1/25/2016 Post a comment Steve Sandler's session on engineering bloopers was a hit at DesignCon 2016. In this video, he describes a logic gate whose design makes the chip impossible to properly decouple and about impedances that don’t match.
Alliance Fast Tracks Ethernet Standards, Products News & Analysis 12/10/2015 Post a comment A year after forming, the NBASE-T Alliance is speeding up the
development and standardization Ethernet specifications with the IEEE 802.3bz standard. On its one-year anniversary, the group announced a new MAC-PHY specification and the addition of 14 new members.
Inside NXP Merger: Dos & Don'ts News & Analysis 12/9/2015 7 comments The first instinct for anyone working at chip companies about to go through mergers and acquisitions would be understandably to assume the worst: There goes your job. What should be your next step?
Gas Sensors Penetrate Smartphones News & Analysis 11/5/2015 3 comments Cambridge CMOS Sensors Ltd. claims to have a 1-by-1 millimeter die that can sense any pollution gas, in a package small enough to fit inside any smartphone.
Electromechanical Displays: The Nipkow Disk Engineering Investigations 10/4/2015 Post a comment How to get your oscilloscope to act like this maker favorite: the rotating contraption that makes a 3D display when spinning. Engineer Dennis Feucht has an idea to improve it. Maybe just in time for Halloween.
Compensate For Cable Voltage Droop Blog 9/30/2015 Post a comment Have you ever used an extra-long USB cable to charge your phone or tablet, only to find that it was taking an extra long time to charge? It probably wasn’t your imagination and was a situation that involved excessive voltage drop across the universal serial bus (USB) cable.
GE Connects Industrial IoT News & Analysis 9/30/2015 Post a comment Connecting manufacturing and industry to the Internet is the next great frontier for OEM and manufacturer General Electric. The company showcased analytics platforms alongside hardware at an industrial Internet event.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
