← ScienceWhich consequence results when significant parasitic inductance occurs in the gate drive circuit of a high-frequency MOSFET?
A)Increased gate oxide breakdown risk✓
B)Enhanced switching speed performance
C)Reduced electromagnetic interference (EMI)
D)Improved static power dissipation
💡 Explanation
Gate oxide breakdown risk increases because parasitic inductance interacts with gate capacitance, creating ringing. This inductive ringing leads to voltage overshoot, stressing the gate oxide, thereby increasing the risk to that component rather than alternative behaviours such as suppressing EMI.
