← ScienceWhich risk increases when distributed gate capacitance in high-frequency CMOS circuits becomes excessive?
A)Signal propagation delay increases sharply✓
B)Internal resistance decreases significantly
C)Maximum supply voltage tolerance widens
D)Short-channel effects are greatly suppressed
💡 Explanation
Increased capacitance causes signal propagation delay because a larger charge transfer is required and therefore takes more time; the Elmore delay model explicitly relates delay to capacitance, rather than decreases in internal resistance under normal conditions.
