← ScienceWhich outcome accompanies increased temperature of MOSFETs carrying a saturated signal?
A)Reduced on-state current amplification factor✓
B)Increased gate oxide layer breakdown risk
C)Enhanced electron mobility within channel
D)Lower subthreshold swing voltage requirement
💡 Explanation
Decreased current amplification results because temperature increases phonon scattering, which reduces carrier mobility via the **Drift Velocity Saturation** mechanism; therefore signal amplification decreases, rather than mobility improvements which occur via alternative doping methods.
