Q1. Assume that all transistors are operating in the active region (i.e. all necessary biasing conditions are provided) and $V_A = \infty$ for the transistor. (Please support your solutions with short notes.)
a) What type of feedback is present in the circuit? [10p]
b) Please find the expression for the open loop gain ($v_{out}/v_{in}$), input resistance and the output resistance. (Don't forget to include the loading effect in your analysis) [15p]
c) What is the feedback factor, K? [10p]
d) Plese find the expressions for the closed-loop gain, input resistance and the output resistance. [15p]
