I'm studying about bjt transistors and I have a question in fixed bias circuit below :
When I analyzed this circuit first I calculated DC response but I didn't do that I measure DC response when V2 is 0 found that :
Ib=15.7uA , Ic = 3.73 mA.
And I calculated r'e :
( IE approximate to Ic )
= 26mV/IE.
= 6.67 ohm.
And I find voltage gain from :
A. = (Rc//RL)/r'e
= 4761/6.67
= 713
And I checked in Multisim found that it's not same as I calculated in Multisim they equal to 365 ( How I measure gain is Vout/Vin).
Where is my wrong why it's not same ?
Thank you ( sorry my English is not good )
