Please solve. Thanks
10.5 Find the intrinsic gain A, and the unity-gain fre- quency fr of an n-channel transistor fabricated in a 0.13-µm CMOS process for which L = 0.1 L, ₁ = 400 P cm /V-s, and V = 5 V/um. The device is operated at Voy = 0.2 V. Find A, and fr for devices with L = Lmin 21-min 3Lmin, 4Lmins and 5Lmin. Present your results in a table. (Hint: For fr, use the approximate expression 3μ₂ Vov.) fr~ 4x L² C DIT 05 hog
