I have this homework problem for my electronics class and I'm in need of assistance.
Here is the original problem statement:
This is what I have after drawing the circuit:
My professor always suggests that we start at the output and write it in terms of the first dependent source to the left, but when trying to write V_out, there's two dependent sources.
I'm not sure how to handle that.
Things I tried:
I can't use a current divider to find the voltage across R4 because the series combination (R8 + R2) are not in parallel. And I can't do a KCL at Node H without adding another unknown variable to the mix.
KVL expression for V_out:
Similar as the current divider, I can't write an expression for V_out because there are no KVL loops that don't require me to define even more variables.
Then, all I could figure out to do was start at the input and write equations for the variables that control the dependent sources, but that involved defining even more unknowns. As you can imagine, this got really ugly, really quickly.
All other amplifier circuits we have looked at in class are "linear", in that there aren't two sets of cascaded amplifiers stacked vertically, like in this problem, and I can't find anything like this circuit in the chapter of our textbook.
If anyone could explain an intuitive thought-process or a process to solve a cascaded amplifier circuit like this one, I'd be very grateful. :)
