Proper Name

[Jamie]

I am doing up some doc's on a design but I can't remember the proper
name for this type of output, which is being used in the designed.

Currently I have it in the doc as "common emitter, complementary
totem pole output" however, I did remember an official name for this
type of output, which I can't seem to bring to mind!

Without any thought I would have called it a complementary pair output.
But for bipolar that would normally be associated with output
transistors with their emitters connected. However a complementary CMOS
output would use a similar topology with the sources connected to the
power supplies.

Otherwise I'm not sure if it's a practical arrangement with bipolars
such that it is worthy of a name!!

For info:

I use that lay out when I want to get close to the rails and do basic
current limiting control.

** There is not one "correct" name.

"Complementary common emitter" output stage is the most precise.

"Complementary collector output " is another, that is OK.

Also, some will use the name " complementary Sziklai output stage" to
really impress.

What you schem shows is incomplete - so it has no name.

Perhaps (a type of) "half-bridge"?

This is often referred to by its marketing term: Rail-to-rail output
stage or RR output stage.

** No it isn't.

You are a fucking IDIOT.

Piss off.

Wikipedia offers some names:
<http://en.wikipedia.org/wiki/Push-pull_output>
Looks like "Symmetrical push-pull" is the closest.
<http://en.wikipedia.org/wiki/Push–pull_output#Symmetrical_push.E2.80.93pull>

Providing the 2 bases are tighed up, we (in France at least) call this
schematic "push-pull". Was very popular for audio output.

** No it isn't.

Yes, it is. See figure 4.

The do call it complementary common emitter drive, no one could misunderstand that.

** WTF happened to the context ??????????????

Yes, it is. See figure 4.

** Totally IRRELEVANT !!!!!!!

YOU fucking STUPID, OVER-SNIPPING TWAT

It's very relevant since complementary common emitter/source output drive is the basis of RRO technology, not the whole thing because there are very clever ways involved in driving the pair, but it's the starting point.
