pinch-off
pinch-off Electronics. Also pinch off. [f. vbl. phr. to pinch off s.v. pinch v. 2 e.] In a field-effect transistor, the meeting of the two non-conducting depletion layers that border the channel, such that little further increase in current is achieved by increasing the drain voltage. Freq. attrib.,...

Pinch-off voltage
Pinch-off voltage may refer to one of two different characteristics of a transistor:
in insulated-gate field-effect transistors (IGFET), "pinch-off" in junction field-effect transistors (JFETs), "pinch-off" refers to the threshold voltage below which the transistor turns off.

Channel length modulation
To understand the effect, first the notion of pinch-off of the channel is introduced. Instead of flowing in a channel, beyond the pinch-off point the carriers flow in a subsurface pattern made possible because the drain and the gate both

Voltage-controlled resistor
Typically, JFETs when they are packaged as VCRs often have high pinch-off voltages, which result in a greater dynamic resistance range. For values of VGS near zero, the drain-to-source voltage linearization voltage or triode breakpoint is much higher than when VGS levels are near the pinch-off

Field-effect transistor
This is called "pinch-off", and the voltage at which it occurs is called the "pinch-off voltage". If drain-to-source voltage is increased further, the pinch-off point of the channel begins to move away from the drain towards the source.

عند بداية منطقة التشبع حيث تكون جهد المصب مساويا تقريبا من فرق الجهد VGS – Vth توجد منطقة تسمى «منطقة التقاط» pinch-off تشير إلى عدم تكوّن قناة قرب المصب

金属氧化物半导体场效电晶体
但是随著汲极电压增加，超过闸极电压时，会使得接近汲极区的反转层电荷为零，此处的通道消失（如图），这种状况称之为夹止（pinch-off）。在这种状况下，由源极出发的载子经由通道到达夹止点时，会被注入汲极周围的空间电荷区（space charge region），再被电场扫入汲极。

Threshold voltage
When referring to a junction field-effect transistor (JFET), the threshold voltage is often called pinch-off voltage instead.
