John L. Waugaman

John L. Waugaman’s love of electronics began when he built a crystal set at age 10 with his father’s help. Earning a BSEE from Carnegie-Mellon University led to a 30-year career in industry designing product inspection equipment and four patents.

After being RIF’d, he spent the next 20 years as a consultant specializing in analog design in industrial and military projects. Now he’s retired, sort of, but still designing. It’s in his blood, he guess.

  1. A simpler circuit for characterizing JFETs
    The circuit presented by Cor van Rij (Ref. 1) for characterizing JFETs is a clever solution. Noteworthy is the use of a five-pin test socket wired to accommodate all of the possible JFET pinout arrangements. This idea uses that socket arrangement in a simpler circuit. The...
