A Low-Cost Analog Circuit Implementation of the Jiles-Atherton Hysteresis Model

We show the design of a broadband, fully analog circuit for simulating the hysteretic <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">B</i> − <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">H</i> characteristics of magnetic core materials closely following the Jiles-Atherton model using standard electronic components. The circuit can be used for real-time demonstration of the Jiles-Atherton model for educational purposes, or to mimic sound effects of overdriven output transformers in guitar valve amps.
