← ScienceWhich effect happens when parasitic capacitance resonates destructively in high-speed digital circuits?
A)Ground bounce voltage spikes✓
B)Increased transistor switching speed
C)Enhanced signal integrity margin
D)Reduced electromagnetic interference emissions
💡 Explanation
Ground bounce voltage spikes occur due to inductive impedance combining with parasitic capacitance, triggering unwanted series resonance; this resonance leads to oscillation rather than clean signal transmission; therefore, voltage spiking occurs, rather than EMI reduction
