Abstract

UN METODO Y CIRCUITO PARA GENERAR UN SEÑAL DE SALIDA REPRESENTATIVA DE LA CORRIENTE DE BOMBEO REQUERIDA PARA IGUALAR LA DIFUSION DE OXIGENO ENTRE LA CELULA SENSORA (112) Y LA CELULA DE BOMBEO (101) DE UN SENSOR PROPORCIONAL DE CONCENTRACION DE ION DE OXIGENO COLOCADO EN EL SISTEMA DE ESCAPE DE UN MOTOR DE COMBUSTION INTERNA. SE GENERA UNA CORRIENTE DE REPLICACION (IPREP), AISLADA PERO REPRESENTATIVA DE LA CORRIENTE DE BOMBEO. LA CORRIENTE DE REPLICACION PASA ENTONCES A TRAVES DE UNA IMPEDANCIA DE CARGA PARA GENERAR LA SEÑAL DE SALIDA. LA CORRIENTE DE REPLICACION SE GENERA SIMULTANEAMENTE CON, PERO AISLADA DE LA CORRIENTE DE BOMBEO (IP), ELIMINANDO ASI LA NECESIDAD DE UNA AMPLIFICACION SEPARADA DE UNA VERSION DETECTADA DE LA CORRIENTE DE BOMBEO.
