Abstract

Un dispositivo convertidor de analógico a digital, caracterizado porque el convertidor de analógico a digital comprende una pluralidad de etapas conectadas en serie, cada una de cuyas etapas comprende medios para determinar la diferencia entre los valores de corrientes de entrada primera y segunda aplicadas a dichos medios, y para valores positivos de dicha diferencia, transferir a una salida una corriente que es proporcional a dicha diferencia, estando constituida la primera corriente de entrada de una etapa siguiente por la corriente en dicha salida de una etapa que le precede, y medios para detectar la polaridad de dicha diferencia.
