A novel switched-current sorter based on magnitude

Abstract

A novel switched-current mode sorter based on magnitude is proposed. In this sorter, switched-current circuit is used to track/hold input signals. Symmetric winner-take-all network is employed to find maximum current. Then, sorted currents based on magnitude are outputted in time-shared way. This sorter has a simple and flexible structure. It has wide current input/output range. Results of experiment show that the deviation of output current from the corresponding input current is small and the sorting resolution is high.
