dc.description.abstractThis paper presents a circuit design technique suitable for the realization of winner-take-all (WTA), maximum (MAX), looser-take-all (LTA), and minimum (MIN) circuits. The technique presented is based on current replication and comparison. Traditional techniques rely on the matching of an N transistors array, where N is the number of system inputs. This implies that when N increases, as the size of the circuit and the distance between transistors will also increase, transistor matching degradation and loss of precision in the overall system performance will result. Furthermore, when multichip systems are required, the transistor matching is even worse and performance is drastically degraded. The technique presented in this paper does not rely on the proper matching of N transistors, but on the precise replication and comparison of currents. This can be performed by current mirrors with a limited number of outputs. Thus, N can increase without degrading the precision, even if the system is distributed among several chips. Also, the different chips constituting the system can be of different foundries without degrading the overall system precision. Experimental results that attest these facts are presented.es
