Abstract

En un generador de diente de sierra vertical (18), un tiempo final (TFIN) de una porcion de retrazo de una señal de diente de sierra vertical, se controla mediante una señal de salida (112a) de un comparador (19). El comparador tiene una primera terminal de entrada (inversora) que responde a un voltaje de referencia (VBAJO), y a una segunda terminal de entrada (no inversora) que responde a la señal de diente de sierra. El voltaje de referencia se acopla con una terminal de entrada (base del Q7) de un amplificador (Q5, Q6, Q7, Q8) de un integrador, que genera la señal de diente de sierra. Cualquier componente de señal de alteracion en el voltaje de referencia se sobrepone en la señal de diente de sierra. Debido a que se desarrolla el mismo componente de señal de alteracion simultáneamente en ambas terminales de entrada del comparador, se proporciona un alto grado de rechazo de modo comun con respecto al componente de la señal de alteracion.
