    Abstract: The present invention relates to an operational amplifier comprising an input-stage circuit, a floating current mirror circuit, and an output-stage circuit. The input-stage circuit receives an input signal and produces a control signal. The floating current mirror circuit is coupled to the input-stage circuit, and produces a mirror current according to the control signal. The output-stage circuit is coupled to the floating current mirror circuit, and produces a driving signal according to the mirror current. When the operational amplifier is operating in the static mode, the output-stage circuit further produces a static current according to the mirror current. Thereby, by using the floating current mirror circuit, the purpose of low power consumption can be achieved while driving to the high-voltage mode or to the low-voltage mode.
