In the first of three parts, Andy hypothesizes that the K2-W Analog Computer Op Amp’s design has some unrevealed mad science in its input-stage design.
After a brief review of the history of the K2-W vacuum-tube op amp, an LTspice model is used to create its schematic in preparation for SPICE simulation.
Fortify’s 3D-printing technology is leveraged to create gradient index refracted lenses for a range of applications, especially those built with SWaP-C in mind.
A brief overview of the history and operating principles of vacuum tubes is discussed, after which Dr. Stephen Dyer shows how to model them in SPICE in their active region of ...
