Integrity Problems For Edge Devices

Battery-powered edge devices need to save every picojoule of energy they can, which often means running at very low voltages. This can create signal and power integrity issues normally seen at the very latest technology nodes. But because these tend to be lower-volume, lower-cost devices, developers often cannot afford to perform the same level of analysis on these devices. Noise can come in... » read more

Rapid Optimization of Electrical and Thermal Characteristics of Electric Vehicle Batteries

Battery powered electric vehicles (EVs) and hybrid electric vehicles (HEVs) have been gaining market share as the public’s environmental concerns and the depletion of fossil fuels drive the demand for better fuel efficiency. But great improvements in the mileage one can drive before recharging, a faster recharging method, and the creation of a recharging infrastructure akin to today’s gas s... » read more

Power/Performance Bits: Nov 28

Deep learning to detect nuclear reactor cracks Inspecting nuclear power plant components for cracks is critical to preventing leaks, as well as to control in maintenance costs. But the current vision-based crack detection approaches are not very effective. Moreover, they are prone to human error, which in the case of nuclear power can be disastrous. To address this problem, Purdue Universit... » read more

Tech Talk: Comparing Smart Phones

What makes one smart phone last longer on a charge than another? The answer may surprise you. Low-Power Engineering talks with Cary Chin, director of technical marketing for low-power solutions at Synopsys, about what his months of research have shown. [youtube vid=BUefmd_oFp8] » read more

Power Management Trumps Battery Technology

By Ann Steffora Mutschler The lithium-ion battery has the power to ruin someone’s day, especially when it dies and cannot be charged, not to mention occasional thermal runaways that literally cause explosions. For a technology that is about 30 years old, and approaching its limits, it is mind-boggling that the best brains on the planet haven’t come up with a technological superior alternat... » read more

Redefining Performance In Mobile Devices

By Ann Steffora Mutschler While mobile product trends can be reliably unpredictable, devices are definitely moving towards supporting more software-based browsers, plug-ins for browsers, and downloaded codecs to go to browsers. This results in coming up with a best guess for performance targets. Throw power tradeoffs into the mix and things really start to get interesting. In terms of defin... » read more

Battery Progress Inches Forward

By Ed Sperling Chip companies that have been betting the future on better battery technology and holding off on the often painful process of reducing voltage should probably start rethinking their plans. Battery technology is not expected to improve by more than 3% per year, and even that may slow. Compared with the chip side, there are no breakthrough materials such as halfnium or techno... » read more

Making Batteries Better

By Brian Fuller The world has changed dramatically in the 209 years since Alessandro Volta hunched over his table by candlelight and figured out how to capture energy in his voltaic pile, the first electric battery. What has changed little, however, is the battery itself. Since Volta’s conception, the battery has remained a cell with negative and positive electrodes, an electrolyte, and... » read more

Minimizing Power Consumption In Next-Generation Mobile Devices

By Cheryl Ajluni Today’s consumers continually demand ever more efficient and reliable means of mobile communication. At the same time, the wireless industry is evolving toward higher data rates and capacities. Both of these trends present a wealth of opportunity for innovative system engineers looking to design the next generation of mobile communication devices. They also pose some inter... » read more
