The n- channel E-MOSFET has the following parameters.

$V_{GS}=3v, V_T = 1V, K= 0.15 mA/V^2, \lambda = 0.03V^{-1}, V_{DS}=8V$

Calculate i) Drain current ii) The output rsistance.

Given : VGS= 3V , VT = 1V, k = 0.15 mA/v2 ,λ = 0.03v-1 ,and VDS = 8V

Drain Current (IDQ) = k [(VGS - VT )2 (1+λ VDS )]

IDQ = 0.15[(3 -1 )2 (1+ 0.03× 8)]

IDQ = 0.744 mA

IDQ = 0.744 mA

The output resistance (ro) = 1/(λ IDQ )

ro = 1/((0.03×0.744×10^(-3) )

ro= 44.802 KΩ.

ro= 44.802 KΩ.
