For the circuit below, assume kn′ = 100 uA/V2, and kp′ = 50 uA/V2, Vtn = |Vtp| = 1 V (a) Find the DC drain currents (ID) and verify operating regions of all transistors. (b) Find the small-signal transfer function (vo/vi), for λn = |λp| = 0. (c) Repeat part (b) for λn = |λp| = 0.1 V−1 Simulate the circuits using MULTISIM to verify your results. Provide all necessary plots. Use NMOS transistors for simulation.
