Hi all, I'm having trouble to solve an exercise about class A output stage.
This is my circuit
http://www.imagestoring.net/show.php/6472_classea.png.html
I need to calculate the VBB and I have to do it without the beta from the transistor.
My first idea was using beta with Ic / Ib = Beta and with the value of Rb I should know.
My second idea is none.. Can you give me some ideia to solve this?
All I know is :
I_CQ = Icmax/2
Icmax-> max collector current
I think I_CQ will be the current on the transistor ?!?
V_CEQ = Vcc/2
And I think V_CEQ will be the voltage between the collector and the emitter.
