← TechnologyWhich performance issue is observed when base-emitter junction temperature rises in a BJT-based amplifier?
A)Thermal runaway escalation occurs rapidly✓
B)Current gain stabilizes unexpectedly
C)Cutoff frequency increases sharply
D)Reverse saturation minimizes noticeably
💡 Explanation
Thermal runaway appears because increased temperature amplifies the collector current; therefore *positive feedback* accelerates thermal dissipation, making the overall circuit efficiency decrease, rather than maintaining stable operation or improving parameters.
