Abstract:
An operational amplifier circuit configured to drive a load is provided. The operational amplifier circuit includes an output stage module. The output stage module includes a detection circuit and an output stage circuit. The detection circuit is configured to detect a current output voltage and a previous output voltage based on a comparison result of a current input voltage and the current output voltage. The detection circuit enhances a charge capacity or a discharge capacity of the output stage circuit for the load based on a detection result. Furthermore, a method for enhancing the driving capacity of the operational amplifier circuit is also provided.
