Which disruption results when parasitic capacitance couples gate signals in high-speed CMOS?

A)Unintended transistor firing ('glitching')
B)Increased static power dissipation
C)Signal rise/fall time improvement
D)Reduced electromagnetic interference (EMI)

💡 Explanation

Unintended transistor firing occurs because capacitive coupling implements unwanted charging/discharging paths, leading to spurious state changes. Therefore, 'glitching' rises because it affects undesired activation, rather than quiescent power losses or mitigated emissions.
