Abstract

Circuito eléctrico y método para eliminar la influencia de una caída de voltaje. La invención resuelve un problema de compensar una caída de voltaje indeseada a lo largo de un conductor eléctrico de corriente CC (10) conectado a un circuito integrado (20) . El aparato de la invención incluye un amplificador diferencial (106) conectado entre un suministro de voltaje (105) y el conductor eléctrico (10) desde el circuito integrado (20) que es dañado por la caída de voltaje. Un terminal de entrada (103) del amplificador (106) está conectado al cable de suministro (105) y un terminal de salida (109) del amplificador (106) está conectado al conductor eléctrico (10) . La red de alimentación (51) está conectada entre otro terminal de entrada (104) del amplificador (106) y el circuito integrado (20) . Una diferencia de potencial entre los dos terminales de entrada (103, 104) en el amplificador (106) hará que el amplificador (106) ajuste un potencial en el terminal de salida (109) hasta que se compense la caída de voltaje indeseada a lo largo del conductor eléctrico (10) .
