Operational amplifier module and method for enhancing driving capability of operational amplifier circuit
An operational amplifier module including an operational amplifier circuit and a comparator circuit is provided. The operational amplifier circuit includes an input stage circuit and an output stage circuit. The input stage circuit receives an input signal. The output stage circuit is coupled to the input stage circuit for enhancing the driving capability of the input signal. The comparator circuit is coupled to the output stage circuit for receiving the input signal. The comparator circuit determines whether the input signal changes so as to output an enable control signal to the output stage circuit to enhance the driving capability of the operational amplifier circuit. Furthermore, a method for enhancing the driving capability of the foregoing operational amplifier circuit is also provided.
