Amplifier Transient Crossover Distortion Resulting from Temperature Change of Output Power Transistors
The fluctuation of the idle current resulting from temperature increases of power transistors in class-B amplifiers becomes the cause of transient crossover distortion when dynamic input signals such as music sources are applied. This paper explains the cause of this transient crossover distortion and suggests a counter-measure using a bias control circuit with a built-in microprocessor.
