Solution:

QUESTION: 5

(Q.5-Q.7) For each of the circuits shown find the labeled voltages. For all transistors, k_{n}(W/L) = 1 mA/V2, V_{t} = 2V, and λ = 0

5. Find V_{3}

Solution:

V_{3} = 10- 4 * 2 + 1.4 = 3.4v.

QUESTION: 6

Find V_{4} and V_{5}

Solution:

QUESTION: 7

Find V_{1} and V_{2}

Solution:

I_{D} = 1 = ^{1}⁄_{2} * 1 * (V_{GS} – 2)^{2} => V_{GS} = 3.41v.

V_{3} = 3.41v.

QUESTION: 8

(Q.8 & Q.9) For each of the circuits shown find the labeled node voltages. The NMOS transistors have V_{t} = 1 V and k_{n}( W/L ) = 2 mA/V_{2} and λ = 0

Find V_{1} and V_{2}

Solution:

QUESTION: 9

Find V_{3} and V_{4}

Solution:

QUESTION: 10

For the PMOS transistor in the circuit shown k_{n}= 8 µA/V^{2}, W/L = 25,|V_{tp}| = 1V and I = 100μA. For what value of R is V_{SD} = V_{SG}?

Solution:

V_{SG} will be equal to V_{SD} only when the resistance shown is zero or in other words there should not be any resistance.
