WebDrain-induced barrier lowering (DIBL) is a short-channel effect in MOSFETs referring originally to a reduction of threshold voltage of the transistor at higher drain voltages.In a classic planar field-effect transistor with a long channel, the bottleneck in channel formation occurs far enough from the drain contact that it is electrostatically shielded from the drain … Web• The effect of channel‐length modulation is less for a long‐ channel MOSFET than for a short‐channel MOSFET. ... ÆVTH is lower than for a long‐channel MOSFET Drain …
WebDIBL also affects the current vs. drain bias curve in the active mode, causing the current to increase with drain bias, lowering the MOSFET output resistance. This increase is additional to the normal channel length modulation effect on output resistance, and cannot always be modeled as a threshold adjustment. WebDrain Induced Barrier Lowering (DIBL) As seen in the constant potential contour plots, there is more surface potential (ψ s) in the short channel MOSFET more band bending near drain due to the drain eld encroaching into the channel region reduces V THN when drain is biased at higher potential This is called drain induced barrier lowering (DIBL)
