Q2.

In the circuit, $I_{\text{DC}}$ is an ideal current source. The transistors $M_1$ and $M_2$ are assumed to be biased in saturation, wherein $V_{\text{in}}$ is the input signal and $V_{\text{DC}}$ is fixed DC voltage. Both transistors have a small signal resistance of $r_{ds}$ and trans-conductance of $g_m$ . The small signal output impedance of this circuit is
