In a mosfet long channel refers to
Drain-induced barrier lowering (DIBL) is a short-channel effect in MOSFETs referring originally to a reduction of threshold voltage of the transistor at higher drain voltages. In a classic planar field-effect transistor with a long channel, the bottleneck in channel formation occurs far enough from the drain contact that it is electrostatically shielded from the drain by the combination of the substrate … WebMAX4864LELT+T PDF技术资料下载 MAX4864LELT+T 供应信息 Overvoltage Protection Controllers with Reverse Polarity Protection ADAPTER -28V TO +28V 1µF IN GATEP GATEN P N N OUTPUT that if the input is actually pulled low, the output will also be pulled low due to the parasitic body diode in the MOSFET.

Thus, neither the length nor the voltage across the inversion layer change beyond the pinch-off, resulting in a drain current independent of drain bias. Consequently, the drain current saturates. birchley st car park st helens
