The Cut-Off region is also called a Pinch-off region where the gate voltage Vgs is enough to force the JFET to behave as an open circuit since the resistance of the channel is maximum. C: Saturation Region: The saturation region is also called the active region where conduction of the de...
The main principle of the MOSFET device is to be able to control the voltage and current flow between the source and drain terminals. It works almost like a switch and the functionality of the device is based on the MOS capacitor. The MOS capacitor is the main part of MOSFET. The semicon...
joining the depletion region at the p-n junction on the other side of the channel – under this condition, the channel cannot carry current between drain and source. This occurrence is comparable to that of pinch-off occurring in a JFET at the drain end of the channel. The pinch...
When Vds increases above the pinch-off value, the voltage drop along the channel stays constant at the Vds value ofequation 4. The drain current Id is also constant (at saturation level), no matter the magnitude of Vds. Therefore, both the voltage drop across the channel and the current t...

(4) When VGS is 0 and VDS is increased to a certain value, the channel near the drain is pinched off to form a pinch-off region. VDS↑→ID unchanged What are the three poles of the mos tube and the method of determination?
s pinch-off voltage varies significantly depending on the type employed and the circuit’s source and drain. The JFET gate current, which is the reverse leakage of the gate-to-channel junction, is similar to a MOSFET but significantly less than a bipolar junction transistor. Since the JFET ...
