← ScienceWhich outcome results when parasitic capacitance shorts in a PCB?
A)Unintended resonant frequency oscillations occur✓
B)Operational amplifier gain stabilizes precisely
C)The clock signal experiences reduced jitter
D)Power supply ripple current reduces smoothly
💡 Explanation
Unintended oscillations occur because when parasitic capacitance bridges traces, resonant circuits can form due to inductive elements; therefore oscillations around the resonant frequency occur, rather than stable gain because feedback loops become unstable with added frequency sensitivity.
