Abstract
A repair operational amplifier circuit including a repair operational amplifier and a slew rate enhancing module. The repair operational amplifier includes an input terminal and an output terminal. The input terminal is used to receive an input signal. The output terminal is used to output an output signal. The slew rate enhancing module is coupled to the input terminal and the output terminal of the repair operational amplifier and used to selectively control the repair operational amplifier to increase a slew rate of the output signal according to whether the slew rate of the output signal is smaller than a default slew rate.
