Abstract

Un convertidor de analógico a digital que comprende un circuito doblador para convertir una señal de entrada monótonamente creciente hasta un cierto valor de la misma en una señal de salida monótonamente creciente o decreciente y, por encima de ese valor, en una señal de salida monótonamente decreciente o creciente, comprendiendo el circuito doblador un primer y un segundo transistores a los cuales está aplicada la señal de entrada en funcionamiento y cuyos emisores están alimentados por una primera y una segunda fuentes de corriente continua, respectivamente, y de cuyos colectores se obtiene la señal de salida por medio de un circuito productor de diferencia, caracterizado porque la señal de entrada está aplicada en funcionamiento al emisor del primer transistor mediante una fuente de corriente, mientras que el emisor del segundo transistor está acoplado al del primer transistor a través de un elemento de umbral y las bases del primero y segundo transistores están conectadas a tensiones continuas tales que en funcionamiento la diferencia de tensión entre ellas es inferior a la tensión de umbral del elemento de umbral.
