A novel extensible current mode sorter based on magnitude is proposed.This sorter not only outputs sorted currents based on magnitude
but also determines the order of input terminals corresponding to the order of input currents magnitude.The time and area complexity of the sorter is O(N).The structure of this sorter is simple
flexible and its scale can be easily extended.This sorter is able to be directly fabricated in a standard digital CMOS process and easily implemented in VLSI technology.
