Also of Interest” and “Elementals” for October 20, 2008

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.

It's 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 a few items of general interest to the engineer, while the second highlights some 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 , Portable Design , 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, at the bottom).

Also of Interest:

Elementals:

  • Using a function generator and an oscilloscope, you can measure gain and phase shift versus frequency in a power supply's control loop::
    “Measure power-supply loop transfer,”
    Test & Measurement World , September 2008
  • The International Electronics Manufacturing Initiative (iNEMI) consortium has initiated projects for assessing functional test and board flexure and for encouraging the use of boundary scan:
    “iNEMI addresses board quality,”
    Test & Measurement World , September 2008
  • Pulsed I-V device characterization can be performed by means of swept or single-pulse measurements, keeping in mind that the test system must be carefully selected and calibrated:
    “Use Pulse I-V Testing To Characterize RF Devices,”
    Microwaves & RF , August 2008
  • Guidance on testing broadband Vivaldi antennas and how to apply those measurement results into improved performance when used in a CAE simulator:
    “Design An X-Band Vivaldi Antenna, Part 2,”
    Microwaves & RF , August 2008

    I think tunnel diode will be great attachment in this article.

    Tunnel diode – semiconductor diode characterized by a small thickness of the pn junction, a very high concentration of dopants on both sides and a negative dynamic resistance for a certain range of polarizing voltages. It was invented in 1957 by the Japanese physicist Leo Esaki (hence sometimes it can be named Esaki diode). During research on semiconductor junctions he noticed their thus far unprecedented feature based on the tunnel phenomenon . This phenomenon causes charge carriers move through the narrow barrier layer at a very low voltage .
