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. Webthe channel region. The height of this barrier is a result of the balance between drift and diffusion current between these two regions. The barrier height for channel carriers should ideally be controlled by the gate voltage to maximize transconductance.
