What happens if the quiescent current is set too high in class AB?
Answer: C
Excess standing current dissipates power at idle and, since the required bias voltage falls as the devices heat, can feed a runaway unless the spreader tracks them. Crossover distortion improves rather than worsening, and neither output power nor bandwidth is much affected. The quiescent current is squeezed between crossover distortion below and dissipation above, so it has an optimum rather than a direction of improvement. Naming the cost of a choice alongside its benefit is what turns a fact into a design decision.
