Pinchoffeffect

夹断电压是漏极到源极的电压，之后漏极到源极的电流变得几乎恒定，JFET进入饱和区域，仅当栅极到源极的电压为零时才这样定义。

When the voltage applied to the drain is increased beyond VSAT, the pinch-off point moves further towards the source, reducing the effective channel length, ...

We call this pinch off. Electrically, the effect of pinch off is that the channel no longer acts like a simple resistor. The current 2. 3 becomes fixed ...
