Question

How does a FET behave when the V-I characteristics are to the left of pinch off for an n-channel FET?

• A. Voltage controlled resistor
• B. Amplifier
• C. Switch
• D. Diode

Hint:

In the ohmic region (to the left of pinch-off), a FET acts as a voltage-controlled resistor, unlike in saturation where it acts as a constant current source.

Answer 1

The Correct Option is A

When the FET is operating to the left of the pinch-off region in the V-I characteristics, it behaves like a voltage controlled resistor. In this region, the current through the FET increases linearly with the applied voltage, and it can be modeled as a resistor whose value is controlled by the gate voltage. Therefore, the correct answer is option (1).
