c. Determine the region (A, B, C, or D) in which the device should be operated to
$V_{out}$
maximize incremental gain, $A_v = \frac{V_{out}}{V_{in}}$
d. Compute the error in incremental voltage, $v_{out}$, (in regions A, B and C) if the second
order term is included in the Taylor series expansion. Explain your answer.
