Which risk increases when a bypass capacitor degrades within a high-frequency amplifier circuit?

A)Increased spurious signal oscillation
B)Dramatic device overheating risk
C)Amplifier's power supply droops
D)Catastrophic transistor base diffusion

💡 Explanation

Spurious oscillation appears because the bypass capacitor no longer shunts high-frequency noise to ground, therefore positive feedback increases amplifier gain at unintended frequencies causing instability, rather than overheating or power supply droop at the intended frequency.
