Q7) Consider the ac equivalent circuit of a CMOS common-source amplifier shown in the figure below. The parameters of the NMOS transistors are VTN = 0.5 V, kn' = 85 μA/V2, (W/L)2,3 = 50 and λ = 0.05 V−1. The parameters of the PMOS transistor are VTP = −0.5 V, kp' = 40 μA/V2, (W/L)1 = 50 and λ = 0.075 V−1. Determine the small-signal voltage gain.
