I'd like to ask how to set fixed bias for this transistor.. It doesn't seem to be working. If anyone know how to calculate it, please tell me.
I wanna adjust two resistor values so that Uce = 5,44V, Ube = 0,655V, Ucc = 12V and Ic (collector current) has to be 2,43 mA.
I tried R2 = (12 – 5,44) / 0,00243 = 2,7kOhm.
But in the second part where I wanna find R1, I don't know Ib (base current). Or can I find it out? I tried looking for BETA, but didn't find anything.
I tried editing Beta in Multisim but I couldn't click Edit Model because it was unclickable.
R1 = (12 – 0,655) / Ib
Any ideas? If yes, please add calculations if you did some and explanation. Thanks forwardly for every sensible comment!
