The region of operation in a FET where the drain current is independent of the drain voltage and only depends on the gate-to-source voltage is called the _______.
saturation region
The correct answer is the saturation region. In a Field Effect Transistor (FET), the saturation region is the operational mode where the drain current becomes independent of the drain-source voltage. Instead, it relies solely on the gate-to-source voltage. In this region, the FET operates as a constant current source, which is critical for applications like amplifiers where stable current is required.
