Each week, the editor of Planet Analog finds items of interest and then features them in two sections, entitled “Also of Interest” and “Elementals”. Each cites items from publications outside the Planet Analog and EETimes portfolios. And we also have an archive of recent weekly Planet Analog Newsletters, as pdf files; see the list at the very bottom.
“Also of Interest” and “Elementals” is an extension of our belief that engineers are interested in on-going tutorial on obviously relevant topics, as well as the serendipity of exploring topics which are not directly related to their jobs, but which will broaden their knowledge and sometimes spurs innovative and creative approaches. The first box highlights items of general interest to the engineer, while the second highlights basic and tutorial electronic-engineering material. Among the publications we check are IEEE Spectrum , Machine Design , Design News , Laser Focus World , EDN , Electronic Design , NASA Tech Briefs , Microwave Journal , RF & Microwaves , and Physics Today , plus others.
Consider these items as “online-only” extras, and worth a look. (Please note: there are also links to the previous weeks' editions, below this week’s items.)
Also of Interest:
- Mechanics-of-materials expertise plus the power of software make short work of complex shaft problems:
“Calculate Deflection in Stepped Shafts the Easy Way,”
Machine Design , June 10, 2010 - E-Stops safely halt equipment motion as rapidly as possible:
“Designing with E-Stop Switches,”
Machine Design , June 24, 2010 - Vibration site surveys can tell you a lot about how to specify equipment for vibration isolation in your laboratory:
“How to determine your vibration-isolation equipment needs,”
Laser Focus World , June 2010 - There has been a panoply of research into the next big thing in quantum dots – those semiconducting artificial atoms that are ubiquitous in fluorescence imaging, biological and chemical sensing, and display applications:
“Quantum Dots Are Finding Their Place in the World,”
Photonics Spectra , April 2010
Elementals:
- Dynamic-phase-injection techniques help to tame tunable active inductors for use in miniature monolithic VCOs that provide low phase noise while operating with low power consumption:
“Active Inductors Tune Low-Noise VCOs,”
Microwaves & RF , April 2010 - Thermal management efforts for high-power PIN diode switches should include a combination of test equipment and software, using thermal imaging and 3D thermal modeling, respectively:
“Taming Temperature In High-Power PIN Switches,”
Microwaves & RF , May 2010 - Silicon diodes and metal-oxide Varistors are used to protect delicate circuit components from electrostatic discharge (ESD) or other transient events. These guidelines can be used when comparing two devices (TVS or MOV) of the same technology:
“Selecting Protection Devices: TVS Diodes vs. Metal-Oxide Varistors,”
Power Electronics Technology , June 2010 - GaN is reputed to be a high voltage technology by leading technologists in that field:
“Where are the High-Voltage GaN Products?,”
Power Electronics Technology , June 2010 - Circuit accommodates the multiple levels of lower I/O voltages that have accompanied advances in process technology:
“Use Logic Level Translation To Match Bidirectional Voltage Swings,”
Electronic Design , May 6, 2010
