Wink If you're not a gênius do not read that..jump!

A lot of good people run away when presented to this little problem....people with degrees told that "no time enough"..... others told me they will answer me later on(never done).....some friends told me that the situation has "no solution".... this is the easier way.

I cannot, but some "golden electronics monsters", related to knowledge, will think that's easy!

But i will give a gift to the challenging one that helped me.... an magnificent problem that you will spend at least 30 minutes thinking if you are a very high Intelectual Quocient.... some people is trying since the 1995!

Question Where is the problem?

Where is the problem?. My brain needs some exercise.
I don't see any problem presented.

Maybe that's why he could never get a answer!

The answer is 42!

So long and thanks for all the fish!

Fool. The answer isn't a number - it's a color. Maybe red.

If you want to know the relative current gain for each of the darling ton sets than that is a fairly easy question, the first one will be around 3000, the second 4875. Of course this will depend also on the bleeder resistors a little (but not a lot), and the rather large range of values you will have for the real life trasistors.

But then, this may also nt be an answer to the question you were asking (although it is an answer to A question).

The answer is to make sure that the circuit they are used in is immune to variations in transistor gain. The "N" and "P" types will always be different at some point, as you have seen. If you built another one, then the gains will be different again. Make it irrelevant. Making R1 & R2 the same in each one will help swamp the differences.

Now you have another answer. What was the question again?
