White Papers TOP STORIES Playing The Voltage Game Lowering the voltage is still seen as the best way to save energy, but getting there is becoming far more complicated. Cell Phone Radiation: Taboo Topic, Interesting Science But it's not just about the design of the device. It also depends on what type of network is being used and where the phone is being held. One On One: ARM CTO Mike Muller A candid interview about the future of Moore's Law and the impact of power and leakage on all future designs. 3D DRAM Makers Inch Closer To Production Mass market for devices is still at least a year away, but big name-supporters and advantages in power and speed point to a big uptick; most technical hurdles are solved. Energy Vs. Power: Energy, Power Optimization Is A System-Level Challenge Last of three parts: Power issues are so pervasive that they touch the entire design team – and must be carefully managed as high in the design process as possible. Why Batteries Don't Last Long Enough The hidden cost of analog: More on-chip real estate means mobile devices now need to support more wireless interfaces while still maintaining high signal-to-noise ratios. AMS Challenges Growing High-k/metal gates and double patterning add to the challenges; but with AMS playing a bigger role in energy-saving measures opportunities grow. More Top Stories NEWS & FEATURES Power Bits: The Swarm Swarm computing kicks into gear; copper could replace silver in solar cells. More News & Features BLOGS/TWITTER Editor's Note The Power Of Analog Understanding analog and its impact on efficiency is about to be put to a new test. Barry's Power Points Speed Demons Not everyone is concerned about power. Competition heats up–literally–for an overclocking world record. Everything Low Power Power Intent Formats Feedback and clarification about CPF, UPF 1.0 and IEEE 1801 — what works, what doesn't and what we don't know. Absolute Power Death Grip iPhone 4S vs. iPhone 4 reception–and what happens when you grip the phone in the wrong place. Power Source Power Delivery Networks Ensuring a robust PDN for low-power designs: Part one Power Awareness Bridging The Gap Tying together power-aware engineering and system-level design is a statement of direction. Some key pieces are still missing. JB's Circuit Conservation of Design Pain Regardless of system-design approach, painful tradeoffs are still needed--usually during integration. WHITE PAPERS Addressing Power And Speed Requirements Of Mobile Devices With Data Converter IP A look at the tradeoffs in the design of pipeline ADCs and how digital gain calibration can provide improvements in power and area. Put Low-Power, Low-Overhead, High-Fidelity Digital Sound In Your Next ASIC Or SOC Digital audio is a critical feature for all sorts of products, but picking the right digital audio codecs and audio enhancement programs can be overwhelming. A Guide To Power-Aware Memory Repair A look at repair methodologies and adapting memory repair to power management schemes such as voltage and power islands. More White Papers

OUR SPONSORS VIDEOS/PODCASTS The benefits of looking at power much, much earlier in the design flow. Intel's Max Domeika talks about migration techniques for the embedded Atom processor. A look at the future of EDA, IP, power, stacked die and the relentless pressure of Moore's Law. More Videos/Podcasts
