 If V I

> V

TN , the transistor is on and initially is biased in the saturation region. As the input voltage V GS increases, the V DS decreases, and the transistor eventually becomes biased in the non saturation region.

2. Digital Logic Gate When the input is high and equal toV DD , the transistor is biased in the non saturation region and the output reaches a low value

3. MOSFET Small-Signal Amplifier

Example :  Multi transistor Circuit: Cascade Configuration

 Multi transistor Circuit: Cascode Configuration
