← ScienceWhich consequence results when trapped charges weaken the gate dielectric field in a MOSFET transistor?
A)Reduced power supply noise
B)Threshold voltage instability✓
C)Increased channel conductivity
D)Improved thermal dissipation
💡 Explanation
Threshold voltage instability occurs because charge trapping within the gate dielectric leads to changes in the effective electric field. Therefore, the voltage required to switch the device changes, rather than other benefits like noise reduction.
