Managing Peak Power


Peak power is becoming a serious design constraint across chips and entire electronic systems as more functionality is added into end devices and the compute and switching infrastructure needed to support them. The issues are a direct result of growing complexity in designs, fixed or shrinking power budgets, and the need to process more data more quickly. In mobile devices, the addition of m... » read more

What’s New In Connected Autos


Connected cars and the Internet of Things go together like peanut butter and jelly. But realizing the future of autonomous vehicles will demand close attention to be paid to cybersecurity, functional-safety standards, and other critical factors. [getkc id="76" kc_name="IoT"] will advance the era of self-driving cars, which currently is dominated by Tesla Motors. At the same time, it will cha... » read more

Performance Increasingly Tied To I/O


Speeding up input and output is becoming a cornerstone for improving performance and lowering power in SoCs and ASICs, particularly as scaling processors and adding more cores produce diminishing returns. While processors of all types continue to improve, the rate of improvement is slowing at each new node. Obtaining the expected 30% to 50% boost in performance and lower power no longer can ... » read more

Car Becomes A Living Platform


Future generations of vehicles will age like any other electronic or mechanical devices, but they also will need to adapt, grow, and change in unexpected ways over time to avoid being hacked, rendered obsolete, or otherwise compromised. This adds a whole new set of challenges never seen before in automotive development, and OEMs are working feverishly to bring system architectures up to ... » read more

How Will 5G Work?


Sumit Tomar, general manager of the Wireless Infrastructure Products Group at RF chip giant Qorvo, sat down with Semiconductor Engineering to discuss the development of next-generation 5G wireless networks and other topics. In 2014, RF Micro Devices and TriQuint merged to form Qorvo. What follows are excerpts of that conversation. SE: 5G, the follow-on to the current wireless standard known ... » read more

The Week In Review: Sept. 3


By Mark LaPedus The cellular chip supplier landscape is littered with corpses. So will 4G lead to the destruction of Qualcomm and Intel? That’s highly unlikely, according to a blog from Strategy Analytics. “With the recent announcement of a multimode LTE chipset from Intel, it seems likely that Qualcomm and Intel will maintain their status as the top two cellular radio chipset suppliers in... » read more

CMOS And SOI Invade RF Front End


By Mark LaPedus The next-generation 4G wireless standard known as long-term evolution (LTE) presents some new and difficult design choices for OEMs. One of the more difficult choices involves the less glamorous, but arguably the most critical part in a handset—the radio-frequency (RF) front-end. Typically, the RF front-end often comes in a module and includes various key components, such ... » read more

Smartphones Dial Up New RF Processes


By Mark LaPedus The rapid shift towards smartphones and tablets is driving the need for new and low-power chips at finer geometries. Today, the latest application processors, integrated basebands and other digital cell-phone chips are 28nm planar devices. And it won’t be long before OEMs incorporate 20nm planar and finFET devices in their systems as a means to reduce power and extend batt... » read more

4G Power Hog?


By Cary Chin After some frustrating inconsistencies in measuring energy efficiency of the new iPad in 3G and 4G LTE modes last month, I decided to start over and take a complete set of data. Although it takes a long time, sometimes it just makes sense to start again. The data I took this month isn’t completely consistent with my past measurements, but it feels like whatever is causing the in... » read more

Return Of The Femtocell


By Cheryl Ajluni Nothing has been left unscathed in the current global economic downturn, and that includes femtocell deployments. It was just last year that femtocells were being proclaimed a 2009 “killer app,” along with LTE and WiMAX. But what was once viewed as the next great thing has instead faced a tough road with more than a few large-scale deployments by major mobile operators be... » read more
