Noise Analysis in Precision Analog Designs

There are articles explaining component-level noise analysis for amplifiers or for analog-to-digital converters (ADCs), but very few that explain how to budget noise or analyze noise from the system level. This paper reviews the basics of noise analysis in precision designs, relates those calculations to system-level specifications such as sensitivity, dynamic range, and resolution, and answers some of the big questions about low-noise design.

Nanotube-Based Device Cooling System

These cooling systems can be used for electronic devices in the computer manufacturing, thermal management, and semiconductor industries.Carbon nanotubes (CNTs) are being studied for use in high-strength/lowweight composites and other applications. Recent research on thermal dissipation materials for high-power electronic devices is generating a lot of interest in various industries. Carbon nano tubes have attracted much attention due to their extraordinary mechanical and unique electronic properties. Computer chips have been subjected to higher and higher thermal loads, and it is challenging to find new ways to perform heat dissipation. As a result, heat dissipation demand for computer systems is increasing dramatically.

Selecting the Right Vent to Extend the Lifetime of Electronic Components in Vehicles

Electronic components are rapidly replacing mechanical parts in automobiles. Suppliers must protect these electronic components from harsh contaminants and temperature fluctuations, to ensure reliable performance. Selecting the right venting solution can help to extend the life of the electronic component.

EADIN Lite Communication Network

DEC is part of the Transformational Tools and Technologies (TTT) project under the Advanced Aeronautics research program. John H. Glenn Research Center, Cleveland, Ohio The distributed engine controls (DEC) task seeks to investigate the capabilities of a distributed network for aircraft engine controls. Traditional aircraft engine control systems use analog systems to communicate with sensors and actuators. The ability to upgrade an engine after manufacture, by swapping out sensors or actuators, is limited due to the analog signal component. Digital signals do not have this limitation, and additionally they do not require dedicated cabling, which may decrease engine weight. To understand the interactions between a new digital network and the engine controller, a representative model of the networks is required.

Iris DSN-Compatible, CubeSat-Compatible Transponder

RF portions are combined with FPGA processing inherited from prior systems, which opens up a series of new possibilities. NASA’s Jet Propulsion Laboratory, Pasadena, California No CubeSat-compatible, Deep Space Network (DSN)-compatible communications and navigation transponder exists at the time of this reporting. In order for CubeSats and other small spacecraft to go into deep space, a DSN-compatible capability is needed.

Cockpit Avionics Upgrade Display Atlas, Generic Display Software, and Electronic Procedure System

This computer training system uses nine screens to mimic avionics controls. Lyndon B. Johnson Space Center, Houston, Texas Modern avionics permit user interfaces on spacecraft to be performed on computer screens instead of with physical controls. This saves a great deal of weight; however, it presents challenges with representing all the various controls and gauges as well as flight procedures and data on the limited screen real estate available in a practical cockpit.
