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. Web5 aug. 2013 · I do not know about simulation but any amplifier device including a MOSFET must be biased to amplify. If you rather use the MOSFET to switch on/off, saturation setting can be useful for a good efficiency. Low-level signal amplifier is usually biased in the "linear" response region; high-level amplification calls for saturation setting but one ...
