MOS Structure Operation MOSStructurePhysics MOS transistors can be of two types- NMOS and PMOS. An NMOS has a lightly doped p-substrate (where there is scarcity of electrons). The metal terminal is called the Gate. The oxide layer (usually SiO2) is an insulator. The p-type substrate is grounded while the gate voltage V G is varied. We will see how the MOS structure behaves as V G is .
