Signaling rate versus cable length: the CAN-bus timing trade-off Design How-To 7/31/2009 1 comment The CAN standard alludes to the trade-off between total bus distance and maximum signaling rate. This article presents specific examples that illustrate why the loop-time (round-trip delay) is an essential measure of network performance. Also included is look at component selection, slew rate control, and timing budget analysis.
Choosing the right battery technology Design How-To 7/31/2009 Post a comment Battery performance, as it relates to runtime and capacity, has become a key market differentiator for consumer electronics. A new line of batteries with technologies like lithium ion and lithium-ion phosphate that offer better performance make the choice of what battery to use harder.

According to Mountz, the patented HD Series Torque Control System is the world's first torque control tool using both air and electric power to set and control torque.
Low power MCU selection criteria and sleep mode implementation Design How-To 7/28/2009 Post a comment Discussed are key MCU low power features such as low power capabilities, flexible clocking systems, event-driven resources that affect its performance and provides selection criteria to choose the right one. Also explored are hardware/software techniques to achieve intelligent power management using low power modes.
Luxemburg lab drives PV efficiency News & Analysis 7/24/2009 Post a comment Scientists from the Luxemburg University Photovoltaics Laboratory have produced thin film solar cells in two different technologies both with very high efficiencies.
Driving higher levels of efficiency in motor designs Design How-To 7/21/2009 Post a comment With energy conservation as a key focus globally, efficiency in motor designs is a growing concern. With governmental regulations urging higher levels of efficiency, motor drives are becoming more sophisticated to meet this efficiency challenge.
Wind power on track for 20% share by 2030 News & Analysis 7/20/2009 Post a comment The U.S. Department of Energy's annual report Wind Power Report claims that with $16 billion invested in 2008 that U.S. wind power development was leading the world, and is on track to contribute 20 percent to U.S. electricity generation by 2030.
Crew remembers Apollo 11, looks to the future News & Analysis 7/20/2009 Post a comment The crew of Apollo 11 observed the 40th anniversary of the first moon landing by remembering those who helped them reach that historic goal. They also challenged future generations to go to the stars while caring for a "fragile" Earth.
How to design a low power wireless sensor network Design How-To 7/17/2009 Post a comment Driven by the demand for "green" technology and better use of power, a new generation of extreme low power wireless networks is being developed for use in machine to machine networks. With this in mind, a new approach towards truly wireless networks is needed.
When good grounds turn bad--isolate! Design How-To 7/17/2009 Post a comment
To make designers aware of these design pitfalls, this article explains where ground potential differences originate in the electrical installation, how ground loops are created unintentionally, and how isolation circumvents both conditions to yield a robust data-transmission system.
Deinterlacing with FPGA for HDTVs Design How-To 7/15/2009 2 comments Interlaced video is a succession of 50 or 60 fields per second, where each field carries only half of the rows that are displayed in each frame of video. This article explores different deinterlacing techniques and examines how FPGAs are increasingly being used for complex deinterlacing functions required for HDTVS.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
