In the circuit, $I_{\mathrm{DC}}$ 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 $V_{D C}$ is fixed DC voltage. Both transistors have a small signal resistance of $r_{d s}$ and trans-conductance of $g_m$. The small signal output impedance of this circuit is GATE EE 2025 Analog Electronics - Small Signal Modeling Question 1 English
