← ScienceWhich consequence results when gate oxide diminishes below 2nm in CMOS?
A)Increased quiescent tunneling current✓
B)Improved transistor gain linearity
C)Lower subthreshold output resistance
D)Reduced gate-source breakdown voltage
💡 Explanation
Quiescent current increases because quantum tunneling dominates as gate oxide thickness decreases, therefore electrons pass directly through the insulating layer rather than being blocked; linearity changes less because drift effects dominate, rather than tunneling's voltage dependence.
