PLEASE SOLVE ON THE PAPER AND CORRECTLY PLEASE Q$1.$ Assume that all transistors are operating in the active region $($i$.$e$.$ all necessary biasing conditions are provided$)$ and V$\_($A$)=$oo for the transistor. $($Please support your solutions with short notes.$)$

a$)$ What type of feedback is present in the circuit? $[10$p$]$

b$)$ Please find the expression for the open loop gain $(\{$:v$\_("$out $")//$v$\_("$in $")),$ input resistance and the output resistance. $($Don$\text{'}$t forget to include the loading effect in your analysis$)[15$p$]$

c$)$ What is the feedback factor, K$?[10$p$]$

d$)$ Plese find the expressions for the closed$-$loop gain, input resistance and the output resistance. $[15$p$]$
