摘要
A current control circuit for controlling a bias current of a class AB operational amplifier includes: a low current source, for generating a low bias current; a high current source, for generating a high bias current, which is greater than the low bias current; and a comparing and selecting unit, coupled to an output terminal of the class AB operational amplifier, for selecting one of the low bias current and the high bias current to output as the bias current according to an output voltage of the class AB OP.
