- microarchitect 15y agoI don't think so. The effect of DIBL is an increase in leakage current with the drain to source voltage. The first-order model I was taught in school was that leakage current not considering DIBL used to be proportional to exp(vgs-vt) but thanks to DIBL leakage is now proportional to exp(vgs - vt + eta*vds). The eta here is the DIBL coefficient, which AFAIK is 0.1 or thereabouts.
- mbell 15y agoThe first-order model falls apart as channel length decreases.
