Zusammenfassung:An operational amplifier circuit includes an operational amplifier and a control circuit. The operational amplifier includes a first input terminal, a second input terminal, and an output terminal connected with the second input terminal. The operational amplifier amplifies a signal provided through the first input terminal, and outputs the amplified signal through the output terminal. The control circuit generates switching signals. In response to the switching signals, the operational amplifier resets the output terminal to a preset voltage, charges the reset output terminal, and compares a voltage of the output terminal charged with a reference voltage provided through the first input terminal to output a comparison voltage.
