Question

Calculate the drain current in an NMOS transistor if Kn = 400 μA/V2, VT N = 0.5 V, λ = 0.02 V−1, VGS = 5 V, and VDS = 6 V. (Round off the answer to two decimal places.)

Answer 1

Drain current = 4050 μA

Step-by-step explanation:

Determine the drain current in an NMOS transistor

Given data :

Kn = 400 μA/V^2

Vt = 0.5 v

λ = 0.02 V^−1

Vgs = 5 V

Vds = 6 v

Id = ?

The drain current can be calculated using the formula below

`I_(D) = (1)/(2) U_(n) C_(OX) (W)/(L) ( V_(GS) - V_(t) ) ^2`

=
`(1)/(2) Kn ( Vgs - Vt)^2`

= 1/2 ( 400 μA/V^2) ( 5 - 0.5 )^2

= (200 μA/V^2) * (20.25 v^2)

= 4050 μA
