Abstract

Perfeccionamientos en circuitos de etapas de entrada para el circuito de control del encendido de automóviles, que alimentan a una señal de salida desde un nodo de entrada, caracterizados porque se dota a cada circuito de etapa de entrada de; un primer y un segundo suministros de voltaje para proporcionar un primer y un segundo voltaje de referencia, respectivamente, donde el primer suministro de voltaje se conecta al nodo de entrada; un primer divisor de corriente para dividir una corriente que fluye del nodo de entrada en una primera corriente y una segunda corriente; un segundo divisor de corriente para dividir una corriente que fluye en el nodo de entrada en una tercera y una cuarta corrientes; un primer capacitor conectado para cargarse por la primera corriente y descargarse por la tercera corriente; un segundo capacitor conectado para cargarse por la segunda corriente y descargarse por la cuarta corriente; y un comparador de voltaje conectado al segundo capacitor y al segundo suministro de voltaje para producir la señal de salida en el nodo de salida.
