Question $6$

For the given push$-$pull circuit below:

$14$ marks

a$.$ Perform the A$.$C$.$ Analysis assuming $r_e^{\text{'}}$ is $0$ ohms. Draw the AC model of the circuit using the $-$model $($or T$-$model$)$ for the transistor. $[1]$

b$.$ Calculate Zin $($loaded$)[1]$

c$.$ Calculate Zout $($unloaded$)[1]$

d$.$ Calculate the unloaded voltage gain, Av$-$NL $[1]$
