Where does the name "Darlington" come from?

Google search for "darlington transistor name" came up with this: [1] - the answer is Bell Labs researcher Sidney Darlington (1906-1997). I'll put a note on the subject page. -- Tim Starling 22:21 Oct 29, 2002 (UTC)

[edit] Spam??

There is something wrong with this article, I've tried to revert he spam, but I still see the spammed version. And it's definitely not in my cache. :-\ —This unsigned comment was added by Pieffe (talk • contribs) .

Seems OK now, last revision I see is 12:10, 16 March 2006 Ugur Basak m (Reverted edits by 80.249.52.136 to last version by Ugur Basak). Femto 13:01, 22 March 2006 (UTC)

[edit] References.

I think a good part of this article is taken from The art of electronics, Horrowiz Hill, 2.16 pag 95. Shall we cite it? Is not verbatim, but is definitely from there. --Pieffe 18:13, 1 April 2006 (UTC)

I didn't write the article, but I did add some information to it using AofE as a reference. However, it was not lifted verbatim, just used as you would use any reference work in an assignment, etc.. So, feel free to add a citation. Graham 08:36, 2 April 2006 (UTC)

[edit] wrong

The current gain should be b1*b2 + b1 + b2 I think.

That can't be right since the current gain should be zero if either b0 or b1 were zero. Roger 19:53, 22 May 2007 (UTC)

HOW TO DESIGN A DARLINGTON AMPLIFIER OF A GIVEN BANDWIDTH?

IS THERE ANY DESIGN FORMULA? —The preceding unsigned comment was added by 61.2.226.29 (talk) 18:32, 10 February 2007 (UTC).

[edit] What exactly is a "Darlington" ??

The article seems indecisive throughout as to the essential nature of a Darlington arrangement. It begins by describing the Darlington as a single device but goes on to suggest that an equivalent configuration of discrete devices can still be a "Darlington".

I'd always understood "Darlington pair" to refer to the circuit arrangement (not to the physical construction), but Darlington's early involvement with integrated packages makes me wonder if he (at least) considered his essential contribution to be the integration. Unfortunately, it seems that he died almost ten years ago, so the obvious source of an authoritative definition is gone. Is there a comparable authority? Mike Shepherd 14:42, 22 May 2007 (UTC)

[edit] Unclear content

The articles states that "many common transistors with high gains have a low current threshold". Can anyone say what this means? I think maybe the intention was to say "low current rating" (no threshold involved). If so, the word "threshold" should go. Mike Shepherd 14:42, 22 May 2007 (UTC)

Since there has been no reply to this in over nine weeks, I have removed the corresponding text. Mike Shepherd 22:41, 27 July 2007 (UTC)

[edit] Darlington transistor vs Darlington pair

I think "Darlington pair" is the more common name for this arrangement and more accurate since it's really two transistors. Any objections to me moving the page? Roger 18:21, 22 May 2007 (UTC)

I support that. Although we may say "Darlington transistor" in casual conversation, the article would be better by avoiding that term. Mike Shepherd 08:14, 24 May 2007 (UTC)
