Offset is IRRELEVANT to output devices you complete MORON !
I know that, and I never claimed otherwise. Offset is a form of
noise, in a sense. And like noise, it is caused almost completely by
the input transistors. I'm well aware of all that.
Do do you know what a 'closed loop' means ?
Yes.
Offset is a form of noise???? This is the first time i have ever
heard that.
Not for me. Its very common interpretation.
There is no engineering reason to look at it that way.
There is to me, and to many others.
is fundamentally a different property with different physics.
Offset is an error. Noise is an error. For example, the standard method of
analysing Sigma-Delta converters is to treat what is, technically, an error
in coding a signal from its actual value, as an additional *noise* source,
that is considered to be unrelated to the signal, when in fact, it is!
I don't see that it matters much where the error comes from, it can be
handled in the same general way.
