"WebDrain induced barrier lowering (DIBL) is the effect the drain voltage on the output conductance and measured threshold voltage. This effect occurs in devices where only the gate length is reduced without properly scaling the other dimensions. It is observed as a variation of the measured threshold voltage with reduced gate length. " - Drain induced barrier lowering原理
