A current sorter has an input section, a comparing section, and a control section. The input section includes a first input unit and a second input unit and generate a first output signal that is indicative of the first input signal and a second output signal that is indicative of a level of the second input signal. The comparing section is coupled with the input section and compares the first output signal and the second output signal to responsively generate a result. The comparing section includes a first comparing unit and a second comparing unit. The control section is coupled with the input section and the comparing section. Furthermore, the control section activates, when receiving an initial load signal, the first input unit, the second input unit, the first comparing unit, and the second comparing unit. Moreover, the control section deactivates, before receiving a second load signal, at least one of the first input unit and the first comparing unit when the first output signal is greater than the second output signal. In addition, the result generated by the comparing section is indicative of a level of the first output signal.
