Data Security Takes Front Seat In Industrial IoT Design


As recently as 10 years ago, protecting Internet of Things (IoT) data was largely an afterthought. Engineers designing IoT and industrial IoT (IIoT) networks were more concerned with ensuring their applications functioned according to design specifications, not with the unintended consequences of releasing potentially sensitive information into the cloud. Today, with billions of sensors an... » read more

Wave Hello To Improved Performance


The International Energy Agency (IEA) estimated that in 2019, approximately 33 percent of all transportation-related CO2 emissions were generated by buses and light to heavy commercial vehicles. Transitioning to electric drives in this sector could clearly have a significant impact on reducing our emissions, but electrifying such demanding vehicles is not an easy task. Many of the concepts... » read more

Radio Frequency Filters For 5G: What They Are And Why They’re Worth The Trouble


By David Haynes, Daniel Shin, and Lidia Vereen­ In the recent blog article "Our wireless world – how Wi-Fi 6 will seamlessly integrate with 5G to keep us connected," David Haynes from our Customer Support Business Group (CSBG) explained how this new generation of wireless technologies will improve our connectivity by using higher frequencies and greater bandwidth than current 4G and Wi-F... » read more

Chipmaking In The Third Dimension


Every few months, new and improved electronics are introduced. They’re typically smaller, smarter, faster, have more bandwidth, are more power-efficient, etc. — all thanks to a new generation of advanced chips and processors. Our digital society has come to expect this steady drip of new devices as sure as the sun will rise tomorrow. Behind the scenes, however, engineers are working feve... » read more

Silicon Lifecycle Management: Actionable Silicon Insights Through Intelligent Measurement And Analysis


Semiconductors have always been challenging to develop, with many waves of innovation in electronic design automation (EDA) tools and fabrication technologies barely keeping ahead of ever-growing design size and sophistication. Once again, the industry has reached a tipping point. The combination of increasing chip and system complexity, coupled with higher expectations for product performance ... » read more

Our Wireless World: How Wi-Fi 6 Will Seamlessly Integrate With 5G To Help Keep Us Connected


Most of us have a good understanding of what 5G is by now. Buzz around the fifth-generation wireless technology has reached a fever pitch – and for good reason.  It offers significantly greater bandwidth, faster connectivity, and lower latency, enabling it to power a much broader range of digital applications than its predecessors. 5G is ushering in a new wave of business and societal trans... » read more

Equipment Perspective At U.S. Senate Hearing On Chipmaking


In March, Lam Research President and CEO Tim Archer testified before the United States Senate Committee on Commerce, Science, and Transportation. The hearing examined a variety of issues including the correlation between American competitiveness and semiconductors, the impact of vulnerabilities in semiconductor supply chains and the importance of CHIPS legislation within the U.S. Innovation a... » read more

Precision Selective Etch And The Path To 3D


Scaling (the shrinking of the tiny devices in chips such as transistors and memory cells) has never been easy, but making the next generation of advanced logic and memory devices a reality requires creating new structures at the atomic scale. When working with dimensions this small, there is little room for variation. Compounding the problem is a need to remove material isotropically, or, un... » read more

PCB Layout Tips For Low Side Gate Drivers With OCP


Our 1ED44173/5/6 are the new low side gate driver ICs that integrate over-current protection (OCP), FAULT status output and enable function. This high integration level is excellent for the digitally controlled Power Factor Correction (PFC) applications with boost topology and ground reference switching. In PFC applications, shunts are used to sense power switch current or DC bus current... » read more
