Pinch-off voltage - Wikipedia

WebPinch-off occurs because, at VSAT, the effective potential between the gate and substrate at the source end of the channel (Veff = VGS) is greater than the potential between the gate and the substrate at the drain end of the channel, which is just the potential needed to form the inversion layer called the threshold voltage (Veff = VGS-VSAT = VTH). WebAs the Gate voltage ( -VGS ) is made more negative, the width of the channel decreases until no more current flows between the Drain and the Source and the FET is said to be “pinched-off” (similar to the cut-off region for a BJT). The voltage at which the channel closes is called the “pinch-off voltage”, ( VP ). Web[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 never off. lawn mowing services in denver co
