Given VDS = 4 V for the configuration shown. Decide:

Expert Solution

Step 1

Solution:

Given Values,

$V_{D S} = 4 V$

$V_{S S} = -3 V V_{D D} = 12 V R_{D} = 3 KΩ R_{S} = 2 KΩ$

Step 2

The calculation of drain current is as follows:

$I_{D} = \frac{V_{D D} - V_{S S} - V_{D S}}{R_{D} + R_{S}}$

By substituting the given values in the above formula, we get:

$I_{D} = \frac{12 - (- 3) - 4}{(3 + 2) \times 10^{3}} = \frac{12 + 3 - 4}{5 \times 10^{3}} = \frac{11}{5 \times 10^{3}} = 2.2 mA$

Step 3

The Drain voltage is calculated as follows:

$V_{D} = V_{D D} - I_{D} R_{D}$

By substituting the known values in the above formula, we get:

$V_{D} = 12 - 2.2 \times 10^{- 3} \times 3 \times 10^{3} = 5.4 V$
