Power Delivery Networks


By Preeti Gupta That power is now at the forefront of semiconductor design is no secret. It is also true that lowering power consumption drives product competitiveness and green technology—even more so in today’s mobile-driven market. But the same drive for lower power also increases the complexity of ensuring the power integrity of a system-on-chip (SoC). The power delivery network (PD... » read more

Cell Phone Radiation: Taboo Topic, Interesting Science


Amid a growing consumer concern for possible health issues associated with radiation, more attention is being paid to what’s being generated by mobile devices—particularly the ones we hold next to our brains. Legislation has been introduced in some parts of the country, with varying success, aimed mainly at informing consumers about the potential risks and giving suggestions for reducing ex... » read more

Playing The Voltage Game


y Ed Sperling Scaling down the voltage to boost battery life and cut energy costs has always been considered the best option, but it’s getting more difficult at advanced nodes and in stacked die packages. The key problems are noise and leakage. Lowering the voltage exacerbates both of them, forcing a rethinking of the whole design process starting at the architectural level and continuing... » read more

Technologies For Power, Signal, Thermal And EMI Sign-off For Chip-Package-PCB Designs


Over the past few years, there has been a marked shift in the way people communicate and use computers. Some of the key changes include the prevalence of mobile internet connected devices such as smartphones and netbooks, the shift to cloud computing using larger centralized data centers, and the increase of electronics in automobiles for guidance, infotainment, and safety control systems. The ... » read more

Five Important Changes That Will Affect Power


By Ed Sperling So far most of the energy savings in SoCs have been achieved using two main approaches—turning off most of the chip most of the time, and changing the materials used to insulate against current leakage. Over the next few years, changes to designs will be more radical, encompass more pieces of a bigger system, and they will be orders of magnitude more effective. From a marke... » read more

EMI Cuts A Wide Swath


By Ann Steffora Mutschler Electromagnetic interference (EMI) cuts across all application segments, whether it’s aerospace and defense and its various tangents, or in a handset, virtually touching a large majority of engineering teams today. The reason this issue affects so many engineering groups is because as modulation schemes become ever more complex they become even more sensitive to ... » read more
