Talk:Transistor model

Catagorized the sections within the article and added subsection Types of Models using reference cited. Would still like to see the Models sections cleaned up, expanded and validated. -- Whiteflye 16:48, 11 July 2006 (UTC)

""Large-signal computer models for devices continually evolve to keep up with changes in technology"" It sounds like a technology develops on it's own and then there are groups of people that try to keep up with developing models for it. This sentence should be reorganized to give a hint, that when someone develops a new technology, it is a natural way to describe it's effects with mathematical equations, or at least with tables of measurement results. These can be rather easily used in simulations. —Preceding unsigned comment added by 130.159.254.2 (talk) 16:40, 11 April 2008 (UTC)

What is a compact model?

The term compact model is used but not explained. --HelgeStenstrom (talk) 08:57, 13 August 2009 (UTC)

You need to ask this guy. Dicklyon (talk) 04:10, 14 August 2009 (UTC)

I tried to make it more clear in the current version. Goitseu (talk) 18:58, 24 September 2022 (UTC)

Mathematical Representation of a Transistor

Is there a model that uses math to describe a transistor? This is kinda what I'm imagining:

---

Let I represent the voltage in the input. Let X be the input that is on this side or something. Let O be that thing's voltage. Let T be that other thing that is the co-efficient of something I totally forgot about. And then then the units.

L-0r3m-1p SUM of that thing there = DO-L+OR.

Yes, there is; see Transistor_model#Popular_models. Probably these are all more complicated than what you're looking for. Over limited ranges of operation, there are very simple models that people use (e.g. collector current = beta * (base current)), but if you write the math you need to at least write the conditions for applicability, and the next thing you'd want to know is what happens when the conditions are not satisfied, and pretty soon you've got the Eber–Molls model or the Gummel–Poon model or something similarly complicated.
