I've got some questions about the solutions given to part b) and c) to this particular problem.
See figure attached for problem statement, given solution, and my solution.
For part b,
Everything makes sense up to the point where he obtains Vo = 5mV and I = 0.5uA and thus iD = 0.25uA.
Now we want the diode currents iD to remain within 10% of their DC value. For this we note that the smallest value of I will be when it decrease by 10%
So Ismall = 0.5uA - (0.1 * 0.5uA) = 0.45uA.
Am I incorrect in thinking this way?
Also, for part c it seems to me that the largest vo obtainable is 11V, 1v above its typical value of 10v.
Why are they giving 1V as the max output signal? Are they referring to the largest deviation the output signal can have? Am I confusing something?
Thanks again!
