WebNov 18, 2024 · Pinch Off Voltage In an n channel JFET, if we apply positive potential at drain terminal keeping the source terminal grounded, there is current from drain to source through the channel due to drift of free electrons from source to drain. This current causes a voltage drop along the channel. WebOct 7, 2024 · The pinch-off effect thus leads to photovoltages that are dependent not only on the contact’s work function, but also its size, its geometry and the work function of the surrounding medium. The... WebIf a voltage V D S is now applied, the inversion region will begin to taper and eventually, it will taper so much that it will pinch off, once it has pinched off (it can no longer shrink in height), it will then begin to shrink in length (width) becoming closer and closer to the source.
