Well, as my 1st attempt to solve the 1st exam didn't ended up well, I'm going for the 2nd attempt.
I'm going to post here my 1st exam's circuits and translations as best as I can do and I'll ask for help to solve it. I'll start solving the problems later today when I get home!
1 - Draw the Transfer Function Vo(Is) for the given circuit. The diodes are ideal and the current source goes from -5mA up to 5mA.
2-The following circuit is a filtered rectifier.
a) - Consider the circuit without C1. Draw the voltage waveform at the rectifier entry point (transformer secondary) and voltage waveform at Rload (R1).
b) Consider now the C1 and find it's capacitance so that Vripple is no greater than 2V.
c) For the circuit of the previous problem (b), draw the input voltage, Rload voltage and diode current waveforms.
Consider that Vγ = 0.7V and mark all the key points in the graphic!
3- Find the voltage at point X. Consider Vγ = 0.7.
4- For the following circuit:
a) Find Rb so that current across Rc is 10mA. β=120 for T1 and β=30 for T2. Both T1 and T2 are Silicon.
b)Find the dissipated power for both T's.
5) For the circuit below find Av, Ai, Ri and Ro. hFE = 100 ad hie = 2KΩ
Note: Av is voltage gain, Ai is current gain, Ri is input impedance and Ro is output impedance...
Hope I made my self clear enough so that you can help!
Thanks
