N-Channel MOSFET is a type of metal oxide semiconductor field-effect transistor that is categorized under the field-effect transistors (FET). MOSFET transistor operation is based on the capacitor. This type of transistor is also known as an insulated-gate field-effect transistor (IGFET).A MOSFET also contains a BJT: If the drain current is high, then the voltage across the channel between the source and the drain can also be high, because RDS(on) R D S ( o n) is non-zero. If it's high enough to forward-bias the body-source diode, you don't have a MOSFET anymore: you have a BJT. That's also not what you wanted.Potential variation along the channel illustrating drain induced barrier lowering (DIBL). DIBL results in an increase in drain current at a given VG.

Similar effect takes place in a P-Channel transistor. In the shown circuit the N-Channel FET diode prevents current to flow from the output back to the input in a paralleled supplies configuration.Because of this, this region of operation is called the ohmic region, or the linear region, or the triode region. The terms “ohmic” or “linear” make sense to me because it is acting like a linear resistor at this point.
