Abstract:
A signal sorting device comprising:an input section comprising a first input unit and a second input unit, the first input unit receiving a first input signal to responsively generate a first output signal that is indicative of a level of the first input signal, the second input unit receiving a second input signal to responsively generate a second output signal that is indicative of a level of the second input signal; a comparing section coupled with the input section and configured to compare the first output signal and the second output signal to responsively generate a compared result, the comparing section comprising a first comparing unit and a second comparing unit; a control section coupled with the input section and the comparing section, wherein the control section activates the first input unit, the second input unit, the first comparing unit, and the second comparing unit when receiving an initial load signal and 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, the compared result being indicative of a level of the first output signal when the first output signal is greater than the second output signal.
