Question 1 (3.13)
(a)
The three stages are all separated, so none of the current sources do anything once weve
shorted the voltage source. Then each of the three capacitors see resistance , so

Problem 2:
Separating small-signal (AC) versus bias points (DC) is very different from
looking at super-position because we are no longer looking at a linear system. We
can approximate small regions around specific bias points, but you cannot remove
