Abstract :
An analog circuit that performs a loser-take-all computation is presented. This circuit takes an array of analog input current and produces an array of binary output voltages/currents. The circuit functions such that the output at the node with the minimum input current is a non-zero constant while all of the other outputs are equal to zero. This circuit can also be used to compute the global minimum of the input array. Theory of operation for this circuit is developed and compared with experimental results
