Texas Instruments Incorporated has introduced a new synchronous step-down DC/DC converter with integrated MOSFETs in a 3.5-mm by 3.5-mm HotRod QFN package. The SWIFT 10-A TPS54020 features the highest power density and includes frequency synchronization, 180-degree out-of-phase switching and selectable current limit to power FPGAs, system-on-chip (SoC), DSPs and processors in … [Read more...]
Father of Modern Cell Phone Reflects on Current and Future Developments, Decades After First Cell Phone Call
Yesterday marked the fortieth anniversary of the world’s first public cell phone call by Motorola engineer Marty Cooper to Joel Engel, head of rival research department Bell Labs. The call was placed on a Motorola DynaTAC 8000x, which weighed approximately 2.5 pounds—about ten times the weight of the average modern cell phone—in front of the New York Hilton on Sixth … [Read more...]
High Voltage inverting DC/DC Controller Released
Linear Technology Corporation has introduced the LTC3863, a high voltage inverting DC/DC controller that uses a single inductor to produce a negative voltage from a positive input voltage. The LTC3863, operating over a 3.5V to 60V input supply range, protects against high voltage transients and operates continuously during automotive cold crank and cover a broad range of input … [Read more...]
Let’s Twist Again
Some time ago I introduced the equation for DM radiation from a loop. I also let Howard Johnson make fun of the single ended crowd that do not believe in loops by quoting from one of his articles. (Refer to “Why Digital Engineers Don’t Believe in EMC”, IEEE EMC Society Newsletter, Spring 1998.) The whole article is available on the internet.Anyway, to continue:E = … [Read more...]
Millimeter Wave Market to Surpass $1 Billion by 2018
Texas-based market research company and consulting firm Markets and Markets has released a report that suggests the millimeter wave market could reach roughly $1.2 billion by 2018. According to the report, titled "Millimeter Wave (MM Wave) Market - By Technology, Components (Frequency, Imaging, Radio); Products (MM Scanners, MM RADARs, MM Macro/Small Cell Backhaul); … [Read more...]

“Smart Paper” May Prevent Counterfeiting and Enable Radio Tracking of Classified Documents
Researchers at North Dakota State University (NDSU) in Fargo, ND have developed a process for attaching tiny silicon radio-frequency identification (RFID) chips to paper, enabling the possibility of better preventing currency counterfeiting and more closely tracking the movements of important classified, legal and financial documents. According to Val Marinov, an associate … [Read more...]
Acoustic Time Delay Device Could Reduce Size, Cost and Complexity of Current Phased Array Systems
Researchers from the Georgia Institute of Technology in Atlanta, Ga. have developed a new device that could help reduce the size, cost, complexity and power requirements of current phased array technology. Modern radar systems are depending increasingly on phased-array antennas—a design in which signal beams are directed electronically by grids of solid state … [Read more...]
FCC Opens Inquiry into Updating RF Radiation Standards for Mobile Devices
The Federal Communications Commission (FCC) has announced a review of current radio frequency (RF) exposure policies and is seeking comments from other agencies and health experts regarding whether U.S. standards need to be updated to better protect people from RF radiation. The inquiry comes almost nine months after the Government Accountability Office released a report … [Read more...]
