Hello everyone, here is my lab work and its tasks. Ive done part of them, but Im stuck at some points. Id be grateful if anyone can help.
Im asked:
1.to do bias calculations for transistors Q1 and Q2 and to find IQC1 and IQC2.
2.to calculate AF by t parameter analyses.
please find schematics and my solutions in attached PDF.
1. I calculated collector currents for each transistor by changing with its Thevenin equivalent, assuming both independent from each other. But Im not sure if I could consider Q2 independent because its driven by Q1. How changing with Thevenin is influenced by the ouput of Q1 and by the feedback?
2.As for AF, first I tried to draw an equivalent circuit for the given one, but I got confused with so many resistances and something tells me its incorrect. I cant go further because I dont know how to draw it in a right way
