Second order effects of MOSFET • Body Effect. The effect of bulk-to-source (reverse) bias potential of MOSFET ( ) on the threshold voltage is referred as body effect. (to be explained with the help of figure) The expression for the threshold voltage of a MOSFET with bulk effect is given by
where is the threshold threshold voltage voltage of a MOSFET with zero bulk-to-source potential is bulk effect coefficient co efficient and is surface inversion potential. potential. • Sub threshold region
• Channel length modulation
As we increase the drain voltage in the saturation region, the drain depletion region widens. This has the effect of widening the pinch-off region and thus shrinking the channel by a small amount.
• Mobility variation
• Fowler Nordheim tunnelling When the gate oxide is very thin a current can fl ow from gate to source or drain by electron tunnelling through the gate. This called Fowler ‐ Nordheim tunnelling. I FN

• Drain Punchthrough When the drain voltage is very high w.r.t source, depletion region around drain may extend to the source causing current to flow irrespective of the gate voltage (even if it is zero). • Impact Ionization Hot electrons. As gate length of MOS is reduced, electric field at drain in saturation increases. For submicron gate length , field can become so high that electrons are imparted with enough energy to become HOT. These hot electrons impact the drain, dislodging holes that a re then swept toward the negatively charged substrate and appear as substrate current. This effect is known as impact ionization.
