Question

Consider an ideal op-amp circuit as shown in the figure below:

The MOS circuit is ideal with $K_{n} = \frac{μ_{n} C_{o x} W}{2 L} = 10^{- 3} A / V^{2}$ and the value of threshold voltage $V_{T} = 1 V$ , then the value of output voltage $V_{0}$ is equal to ______ $V$ .
-2

Open in App

Solution

The correct option is A -2

$I_{D} = K_{n} (V_{G S} - V_{T})^{2}$
$V_{G S} = V_{G} - V_{S} = 5 V - 2 V = 3 V$ $(∵ V_{S} = 2 V$ due to virtual ground $)$
Now, $I_{D} = 10^{- 3} (3 - 1)^{2}$
$I_{D} = 4 m A$
$∴ V_{0} = V_{S} - I_{D} R_{f} = 2 - I_{D} R_{f}$
$= 2 - 4 \times 10^{- 3} \times 1 \times 10^{3}$
$= - 2 V$
