Cut off region in mosfet
http://web.mit.edu/6.012/www/SP07-L10.pdf WebThe cutoff voltage (V GS,off ), to turn a transistor off, is applied to the gate-source region of the FET transistor. It is the particular gate-source voltage where the JFET acts like an open circuit. For N-channel JFET, the cutoff …

WebWhen 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. The device operates in the cut-off region (off-state) when v GS < V Th, resulting in no induced channel. WebIn practical terms, the operation modes describe how the drain current (I D) reacts to a variation in the drain to source voltage (V DS), and are key to understand the MOSFET applications. In the cut-off region the transistor acts as an open-circuit between drain and source, in the linear region the relation between V DS and I D is almost ohmic ...
