But in a more complicated path, consider I-V in the saturation region ... WebSubthreshold slope. The subthreshold slope is a feature of a MOSFET 's current–voltage characteristic . In the subthreshold region, the drain current behaviour – though being controlled by the gate terminal – is similar to the exponentially decreasing current of a forward biased diode. Therefore a plot of drain current versus gate voltage ...
The threshold voltage, commonly abbreviated as Vth or VGS(th), of a field-effect transistor (FET) is the minimum gate-to-source voltage (VGS) that is needed to create a conducting path between the source and drain terminals. It is an important scaling factor to maintain power efficiency. When referring to a junction field-effect transistor (JFET), the threshold voltage is often called pinch-off voltage instead. This is somewhat confusing since pinch off applied to insulated-gate fi… WebJul 1, 2024 · Thus, the final expression for threshold voltage, V th of NC-JL FinFET is obtained by simplifying equations (21), (48) and is given below: (49) V t h = ψ B C P m i …
