Architecture for an Intermediate-Frequency Digital Downconversion and Data Distribution Network
Posted in Briefs, Electronics on Saturday, 30 April 2016
Developed originally for Deep Space Network downlink receivers, applications include high-speed digital receivers for cellular networks. NASA’s Jet Propulsion Laboratory, Pasadena, California NASA’s Deep Space Network (DSN) is looking to modernize aging downlink receivers for telemetry, tracking, and radio science. It is looking to replace multiple types of custom-built, special-purpose receivers with a unified receiver architecture that can support the various downlink data types. As part of this modernization, it is desired to only digitize the data once and then distribute the data using commercial switching network technology to multiple back-end receiver processing hardware and software. The main problem to be solved is how to distribute efficiently and flexibly high-bandwidth intermediate-frequency (100 to 600 MHz) digitized signals across a signal processing center for use in the DSN.
Creating the World’s Smallest Diode
Posted in News, Electronic Components, Electronics on Wednesday, 27 April 2016
Engineers are struggling to shrink the silicon used in processors to power increasingly smaller computing hardware and are rapidly reaching the point where silicon’s performance starts to degrade due to its size. To move beyond the material’s physical limitations, researchers at Ben-Gurion University of the Negev in Israel and the University of Georgia, Athens, have discovered how to use a single molecule of DNA to create the world’s smallest diode, which controls the flow of electricity by allowing it to travel in just one direction.
Engineers Embroider Wearable Antennas

Researchers at The Ohio State University have embroidered circuits into fabric with 0.1 mm precision -- an ideal size for integrating sensors and electronic components into clothing. The achievement supports the development of new wearable technology, including a bandage that monitors tissue or a flexible fabric cap that senses brain activity.
Miniaturized Electronic Devices as Medical Therapeutics

Ada Poon, an Associate Professor of Electrical Engineering at Stanford University, is pioneering research to develop electronic therapies to heal the body from within, working to add control and feedback for a closed-loop system that could improve therapeutic outcomes. These new electronic devices, which can be programmed to respond to the body’s feedback and modulate their own effects after implantation, are called electroceuticals.

2016’s Best Practices for NPI and NPD Success
Posted in White Papers, Electronics, Electronics & Computers on Friday, 25 March 2016
Smart companies know that well disciplined new product introduction (NPI) processes are critical to success. Yet, even these companies can suffer from NPI failure when important projects, policies, and guidelines are haphazardly managed as clumsy manual processes.
High-Performance MEMS IMU Solutions for Demanding Applications
Posted in White Papers, Electronics, Data Acquisition, Sensors on Wednesday, 23 March 2016
For MEMS IMU applications where the inertial profile is complex and highly dynamic, there are a number of attributes to consider when evaluating capabilities. Evaluating these attributes early in the design cycle provides an advantage over chasing open-ended deliverables, like "as accurate as possible."
