JFET，即结型场效应晶体管，其工作原理中一个关键转折点是"夹断电压"。当栅极-漏极电压（VDS）逐渐增大，电流ID呈现出一个显著变化点，此时电流几乎不再随VDS增加，进入**饱和区**或**pinch-off region**。这个点标志着电流的恒定状态，类似于BJT的截止区域，但JFET的饱和是通过耗尽区的扩张实现的。
or pinch-off, voltage and occurs at vGS = VGS(OFF). ... This linear region of operation is called ohmic (or sometimes triode) ... Beyond the knee of
A trench MOSFET with short channel length and super pinch-off regions is disclosed, wherein the super pinch-off regions are implemented by forming at least two type pinch-off regions for punch-through prevention: a first type pinch-off region with a wide mesa width generated between lower ...
The differential equation describing the small signal behavior of a MOSFET channel is derived. Based on the analogy of the channel to distributed transmission lines, which has been very well established in literature, an entirely new RGC line model of MOSFET is presented. The element values of ...
The doping profile of the body is so tailored with ion implantation that a depletion region pinches off to limit current. The body comprises a shallow implant to form a MOS channel and an additional deep implant through a spacer shielding the channel area. Implanted a higher energies and at ...
