Problem $2$

Consider the CE amplifier circuit with feedback of Figure $2.$

Figure $2$: CE Amplifier Circuit with Feedback

$2$a$)20$ points: Draw the AC circuit and perform incremental analysis to calculate the expression for the gain $A=\frac{v_o}{v_i}.$ Show work.

$2$b$)10$ points: Simulate the Circuit of Figure $2$ with $v_i$ activated. Plot $A{v}_i$ and $v_o,$ where $A$ is the value of the theoretical gain. Does the calculation of A look correct? Do you observe now any significant distortion?
