Web22 sep. 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. WebSo with a sufficient positive voltage, VDD, and no voltage (0V) applied to the base, the N-channel JFET is in maximum operation and has the largest current. As we increase the negative voltage, current flows gets reduced until the voltage is so high (negative), that all current flow is stopped. How to Turn Off an N-Channel Depletion-type MOSFET
