What is DIBL?

Short for drain-induced barrier lowering. In short-channel MOSFETs, a higher drain voltage lowers the potential barrier at the source, reducing the threshold voltage and increasing off-state leakage.

Field: MOSFET

  2. Which phenomenon increases off-state leakage because band-to-band tunneling current flows due to the strong field where the gate overlaps the drain?
  3. Which describes a short-channel effect in MOSFETs?
