If we see the physical structure of the … WebAug 26, 2015 · This refers to the voltage Vds that counteracts the opening of the n-channel (NMOS), at the drain end. Since the width of the channel is a function of Vgs - Vtn, the mosfet saturates (pinches off) when Vds is greater or equal than/to Vgs - Vtn. Pinch off voltage is defined as the gate-to-source voltage at which drain-to-source current is zero.

"WebJul 13, 2024 · At pinch-off, there is a tiny channel with a high-density current. In Figure 5, the channel is just at the threshold of pinch-off at the drain end. Increasing Vds beyond Vp lengthens the contact of the two depletion regions along the channel, but Idss remains constant. Under this condition, the JFET acts as a current source.

Pinch off condition

WebPinch Off definition: To separate (something) from something else, using a pinching motion. WebThe pinch off conditions are dependant upon not just Vgs but also Vds. This is from the physics of the situation. What I am not sure of is if Vp is defined for a set of conditions. if that is the case Vp MAY not vary even though you get pinch off as very different Vgs levels depending upon Vds. but that would be because it is a defined level.
