Extreme environments require electronic systems capable of surviving beyond the MIL-STD operating temperature range of -55°C to +125°C. This FAQ series will go to extremes and look at super hot electronics (up to 800°C) and cryogenic electronics. Part one of this series looks at electronics that operate in extreme heat. Part two will look at […]

Fuel cells application challenges and use cases – Virtual Roundtable (part 2 of 2)
In this second part of EEWorld’s “virtual roundtable” discussion on fuel cells, our panelists delve into the impact of the emergence of fuel cells on energy storage compared with conventional rechargeable batteries: What factors determine when fuel cells are more cost-effective than rechargeable batteries? How do the maintenance and monitoring needs of fuel cells compare […]
The difference between noise and jitter
Electronic noise and jitter are closely related phenomena, but they are not the same. While noise typically manifests as amplitude distortion, jitter pertains to timing of digital signals. Either of them can be caused by outside interference or internal sources. Noise can be seen in an oscilloscope time domain display as a noticeable thickening of […]
Fuel cells capabilities and performance – Virtual Roundtable (part 1 of 2)
In this first part of EEWorld’s “virtual roundtable” discussion on fuel cells, our panelists delve into the impact of fuel cells’ emergence compared with conventional rechargeable batteries: What performance advantage do fuel cells have? What is the barrier to large scale deployment? How can fuel cell performance be improved? And how do the environmental or […]
Quantum compasses and optical imaging for global positioning and navigation
There is an emerging demand for a replacement for today’s global navigation satellite systems (GNSS), and especially for the global position system (GPS) in the U.S. Part one of this three-part FAQ series presented several of the shortcomings of today’s GPS technology and some efforts to augment it and improve its performance. Part two presented […]
How to design modular DC-DC systems, Part 3: Stability analysis and decoupling
The previous tutorials in this series showed first how a modular design strategy makes building reliable, adaptable, and high-performing power delivery networks (PDNs) possible when speed is a priority, and second how to design appropriate filtering to meet the needs of DC-DC systems based on switching power modules. This third tutorial will address stability issues […]
eLORAN a terrestrial alternative to GPS
Terrestrial-based hyperbolic navigation technologies predate today’s satellite-based global positioning system (GPS). Starting with developments in the 1930s and 1940s, land-based long-range navigation (LORAN) systems using hyperbolic navigation have been continuously advanced. Today, the enhanced LORAN (eLORAN) system has been offered a more secure alternative to GPS. Hyperbolic navigation technologies were independently developed in the U.S. […]
GPS is a ubiquitous and problematic technology
Much of the world depends upon satellite systems for precise navigation and timing services. The global positioning system (GPS) is a ubiquitous and problematic technology. Global navigation satellite system (GNSS) is the umbrella term for satellite navigation systems that provide autonomous geo-spatial positioning with global coverage. GNSS includes GPS, GLONASS, Galileo, Beidou, and other regional […]
Functional safety for embedded systems – Virtual Roundtable (part 2 of 2)
Hosted by Jeff Shepard, EE World has organized this “virtual roundtable” into “Functional Safety for Embedded Systems.” Panelists include Anders Holmberg (AH), General Manager Embedded Development Tools with IAR Systems, Mike Dow (MD), Senior Product Manager, IoT Security with Silicon Labs, Jim McElroy (JM), VP of sales and marketing at LDRA Technology, Dave Hughes (DH), […]
