WebSir, in case of NMOS, we take threshold voltage Vtn ( it is positive) and in case of PMOS, we take threshold voltage Vtp (it is negative). Transistor is said to be OFF if: NMOS OFF: VgsVtp In normal case, we always take NMOS as reference (its opposite is PMOS), so we can take Vtn as Vt. WebLimitations of Scaled MOSFET Effect of Reducing Channel Length: Drain Induced Barrier Lowering (DIBL) In devices with long channel lengths, the gate is completely responsible for depleting the semiconductor (QB). In very short channel devices, part of the depletion is accomplished by the drain and source bias
