Hello...
I'm studying the attached circuit at the moment and I need help to at least confirm my calcs!
The first problem is to find the transistors Q-point.
I've started by replacing the signal power supplies by their internal impedance.
Then I have evaluated the Iee current by:
Iee = ( V1 - (-Vee) ) / Ree
Iee = ( -0.7 - (-10) ) / 2.2kΩ = 4.227mA
With this value I can also evaluate Ie1 and Ie2, Ie1 = Ie2 = Iee/2, Ie1 = Ie2 = 2.114mA, because the 'left' side of the circuit is theoretically equal to the 'right' side of the circuit.
Can anyone confirm this steps?
