Question 1

What is the formula for the equivalent capacitance considering the Miller Effect?

C<sub>eq</sub> = C<sub>gd</sub>(1 + |A<sub>V</sub>|)
C<sub>eq</sub> = C<sub>gd</sub> × A<sub>V</sub>
C<sub>eq</sub> = |A<sub>V</sub>| + C<sub>gd</sub>

💡 Hint: Remember the interaction between gain and capacitance.

Question 2
