WebAug 2, 2024 · Drain-induced barrier lowering (DIBL) is a short channel effect in MOSFET which is responsible for reduction of threshold voltage and an increase in leakage current at higher drain bias. Increase in drain bias increases the drain depletion width and it starts interacting with source and channel junction which hence reduces the barrier potential. WebN2 - In this paper, we have discussed threshold voltage and drain induced barrier lowering in NCFET. Threshold voltage in NCFET is lower as compared to MOSFET which is mainly because of negative equivalent oxide capacitance in NCFET. Further, we have discussed drain induced barrier lowering in NCFET and MOSFET.
