← ScienceWhich outcome results when parasitic capacitance rises in gallium-nitride amplifiers?
A)Reduced power conversion efficiency✓
B)Increased gate drive current
C)Suppressed harmonic frequency tuning
D)Enhanced substrate cooling demand
💡 Explanation
Increased parasitic capacitance causes energy loss because it raises the reactive power demands within the amplifier through capacitive reactance. Therefore, power conversion efficiency degrades, rather than lowering the gate current under normal operation.
