Q4. (30 points) Given that, VDD = 5 V, VTN = 0.4 V, kn = 100 μA/V2, λn = 0.02 V−1, (WL) = 80, R1 = 4 kΩ, R2 = 0.5 MΩ, R3 = 4.5 MΩ. Find V0. For this part, you can ignore λn. (10 points)What's the output resistance RO? You must use small-signal (ss) model to determine the output resistance. (4 points for SS model and 10 points for the rest)If VDD increase 10% to 5.5 V, will the VO also increase 10% and why? (6 points)

Q4. (30 points) Given that,

V_{D D} = 5 V, V_{T N} = 0.4 V, k_{n} = 100 μ A / V^{2}

λ_{n} = 0.02 V^{- 1}, (\frac{W}{L}) = 80, R_{1} = 4 k Ω, R_{2} = 0.5 M Ω, R_{3} = 4.5 M Ω

Find $V_{0}$ . For this part, you can ignore $λ_{n}$ . ( $10$ points)
What's the output resistance $R_{O}$ ? You must use small-signal (ss) model to determine the output resistance. (4 points for SS model and 10 points for the rest)
If $V_{D D}$ increase $10 %$ to 5.5 V , will the $V_{O}$ also increase $10 %$ and why? ( 6 points)
