Abstract:
A sorter based on magnitude comprising:a plurality of input units, each of which receiving an input voltage for generating a representing signal and a first control signal;a winner-take-all (WTA) circuit receiving a clock signal and the representing signal from each of the input units, for determining which one of said representing signals is the maximum one, and pulling up the determined representing signal to a high level while pulling down the other representing signals to a low level during one operation cycle controlled by the clock signal, said determined representing signal being pulled up to high resulting in said first control signal of the corresponding input unit to be active, while the other representing signals being pulled down to low resulting in the first control signals of the corresponding input units to be inactive, and the determined representing signal being eliminated from the determining operations in sequential operation cycles of the WTA circuit; andan output unit receiving the input voltages and said first control signals for outputting one of the input voltage when the first control signal of the corresponding input unit also receiving the same one of the input voltages is active.
