I’ve written an article titled “A Concise Model for Static Induction Transistor IV Characteristics”, which will appear in Volume 6 of Linear Audio. Linear Audio is a book-zine published twice yearly by Jan Didden. Each issue is packed with quality technical articles you’re sure to enjoy. Copies of Linear Audio can be purchased at www.linearaudio.net.
The new article details a new model for SIT characteristics and includes software you can use to make your own models. I hope you find it useful.
