Abstract
Different winner-take-all (WTA) and loser-take-all (LTA) circuits are studied, and their operations are analyzed in this review. The exclusive operation of the current conveyor, binary tree, and time-domain WTA/LTA architectures, as the most important architectures reported in the literature, are compared from the perspectives of power consumption, speed, and precision.
