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.
Recognizing the nonlinear behavior of the 12AX7 vacuum tube, used in audio and old op-amp applications, Dr. Dyer compares various models for fit to real-world device data.
A successful model-based engineering effort for rugged system infrastructure design will result in shorter development cycles, fewer failures and rework, more innovation, and ...
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 ...
Electromagnetic-interference (EMI) disturbances are on the rise and becoming more intense due to more complex and powerful designs. Engineers can take several courses of action...
What’s the better option: a single-phase controller design or two converters interleaved in a dual-phase design? This article shares insight into the design considerations and...
