WebIn which region MOSFET acts as an amplifier? When used as a switching device, only triode and cut-off regions are used, whereas, when it is used as an amplifier, the MOSFET must operate in the saturation region, which corresponds to the active region in the BJT. WebThe operation of the enhancement-mode MOSFET, or e-MOSFET, can best be described using its I-V characteristics curves shown below. When the input voltage, ( V IN) to the gate of the transistor is zero, the MOSFET conducts virtually no current and the output voltage ( V OUT) is equal to the supply voltage V DD.So the MOSFET is “OFF” operating within its … hal lindsey late great planet earth pdf
