Question

for an n channel mos transistor when the drain and gate terminatal are lied possible operating region is

Answer 1

An n-channel MOS transistor can operate in three possible regions: cutoff, triode, and saturation.

Step-by-step explanation:

An n-channel MOS transistor can operate in different regions depending on the voltages applied to the drain and gate terminals. The possible operating regions are:

1. Cutoff region: This region occurs when both the drain-to-source voltage (Vds) and the gate-to-source voltage (Vgs) are less than the threshold voltage (Vth). In this region, no current flows between the drain and source terminals.
2. Triode region: This region occurs when Vds is greater than Vgs - Vth, but less than or equal to Vgs. In this region, the transistor operates as a voltage-controlled resistor, and the drain current (Id) is proportional to the gate-to-source voltage.
3. Saturation region: This region occurs when both Vds and Vgs are greater than Vgs - Vth. In this region, the transistor operates as a current source, and the drain current is approximately constant.
