Which 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.
