    The fundamentals of PAM4

    edn.com 08 Feb '18, 8pm

    As our society's hunger for data grows—not only more data, but more data delivered faster—older modulation schemes based on NRZ-type encoding grow increasingly inadequate. We need to get data from point A to point B as efficiently as possible, whether that means between chips on a PC ...

  • Kilby files patent for IC, February 6, 1959

    edn.com 06 Feb '18, 3pm

    Jack St. Clair Kilby filed his patent application for the integrated circuit on February 6, 1959, less than six months after the idea came to him. Kilby first demonstrated a multivibrator circuit of discrete silicon elements in late August 1958 to his then-new employer Texas Instrumen...

  • Humidity proves to be the culprit when a medical device experiences an outrageously high #failure rate:

    A lesson in humidity? No sweat

    edn.com 04 Feb '18, 11pm

    Years ago, I started a new job as a senior engineer for a medical-device company that designed and manufactured products for use in cardiology to diagnose heart arrhythmias and other types of patient monitoring. My first assignment was to explain and fix the outrageously high failure ...

    How to avoid measurement mistakes

    edn.com 26 Jan '18, 8pm

    All analog measurements — voltage, current, temperature, humidity, etc. — include some amount of error. Your job is to minimize those errors enough to give your measurement sufficient credibility. EDN has a long history of providing engineers with articles that help you improve measur...

    Active-filter design tools shootout

    edn.com 28 Jan '18, 3pm

    The first level of mismatch to target is the standard resistor value selection. With 5-RC values to choose, and only 3 design targets, the E24 (5% steps) C values are usually chosen first, then the exact R solutions for the 3 design targets are taken to E96 (1% steps) as a final resul...

  • Buck-boost module teardown & test

    edn.com 09 Feb '18, 10pm

    Have I been in electronics for 45 years without this bit of magic being ingrained in me? One FET would dissipate 10A2 ·2mΩ=200mW. So each of two paralleled FETs will dissipate 100mW. But wait. Each FET sees 5A, so: 5A2 ·2mΩ=50mW. That's crazy, but I see what’s happening. Dealing with ...
