What is drain-induced barrier lowering(DIBL)?

The drain voltage Vds creates an electric field that affects the threshold voltage. This drain-induced barrier lowering (DIBL) effect is especially pronounced in short-channel transistors. Drain-induced barrier lowering causes Ids to increase with Vds in saturation, in much the same way as channel length modulation does. Again, this is a bane for analog design but insignificant for most digital circuits. More significantly, DIBL increases subthreshold leakage at high Vds.
