Web1 jun. 2024 · As Drain-source voltage is increased, it attracts the electrons from source end to drain end and current flows from Drain to Source, in this case, we're in the triode region. As the Vds increases, we reach a point where Vds=Vgs-Vth that is pinch-off, at which the current becomes saturated and almost constant current flows. http://web.mit.edu/6.012/www/SP07-L9.pdf

WebWhen referring to a junction field-effect transistor (JFET), the threshold voltage is often called pinch-off voltage instead. [1] [2] This is somewhat confusing since pinch off applied to insulated-gate field-effect transistor (IGFET) refers to the channel pinching that leads to current saturation behaviour under high source–drain bias, even though the current is …
