WebThe source barrier lowering increases also by increasing the drain voltage. Consequently, the threshold voltage gets smaller with increasing drain voltage for short channel … 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.
