Web22 de set. de 2024 · A Field Effect Transistor (FET) is a three-terminal Active semiconductor device, where the output current is controlled by an electric field generated by the input voltage. FETs are also known as unipolar transistors because, unlike bipolar transistors, FETs only have either electrons or holes operating as charge carriers. Web14 de dez. de 2024 · FET is a device that is usually operated in the constant-current portion of its output characteristics. But if it is operated on the region prior to pinch-off (that is where V DS is small, say below 100 mV), it will behave as a voltage-variable resistor (WE). It is due to the fact that in this region drain-to-source resistance R DS can be controlled by …

The JFET is a "pinch off device. It needs a V g s < 0 to create the depletion layer that will "pinch the current off". That cannot happen when V g s = 0. Devices that are off when their V g s = 0 do exist: N_channel MOSFETs. – Bimpelrekkie. dyshelle is in the latency stage if she:
