MOSFET $V_{th} = 1 V, μ_{n} C_{o x} = 0.4 m A / V^{2}, \frac{W}{L} = 20, λ = 0.01 V^{- 1}$ .

For a simple calculation of

I_{D}

, let's assume

I_{D} = 1 m A

without considering

λ

. You still use

r_{o}

for other purposes in this problem.

V_{S} = 4.5 V, V_{D} = 7 V, V_{c C} = 15 V, R_{X} = 100 k Ω, R_{L} = 20 k Ω . C_{1}, C_{2}, C_{3} \approx \infty

Assume the bias current through

R 1

and

R 2

is

2 μ A

(a) (50 pts) Calculate

R_{d}, R_{s}, R_{1}, R_{2}, g_{m}, r_{0}

(b) (50 pts) Calculate

R_{int} R_{out,}, A_{v} (= \frac{v_{out}}{v_{in}})
