← TechnologyWhich outcome occurs when a MOSFET experiences drain-induced barrier lowering?
A)Increased subthreshold leakage current✓
B)Reduced gate oxide breakdown voltage
C)Enhanced channel mobility saturation
D)Improved threshold voltage stability
💡 Explanation
Elevated drain voltage reduces the potential barrier, leading to increased subthreshold leakage current because drain-induced barrier lowering weakens gate control. Therefore leakage increases; rather than a controlled suppression as normally insured by gate insulation.
