Q6. An NMOS cascode amplifier is constructed with a resistive load. The NMOS transistors are sized equally with WL = 5.4 μm 0.36 μm and biased at I = 0.2 mA. (Given: kn′ = 400 μA/V2 and VA′ = 5 V/μm) (a) At what value of RL does the gain become −100 V/V ? (b) What is the voltage gain of the common-source stage at this condition?
