Abstract

UN MARCAPASOS CARDIACO QUE TIENE UN AMPLIFICADOR DE SALIDA (20) QUE RESPONDE A LAS SEÑALES REPRESENTATIVAS DE LA ACTIVIDAD CARDIACA PARA HACER PASAR A LOS ELEMENTOS DE SEÑAL QUE SE ENCUENTRAN EN UNA BANDA DE PASO QUE SE PUEDE VARIAR SELECTIVAMENTE Y PARA VARIAR SELECTIVAMENTE LA GANANCIA DE LA SEÑAL PASADA. UN PAR DE COMPARADORES DE SEÑALES (58,59) QUE CONSTITUYEN AMPLIFICADORES DE CAPACITORES CONMUTADOS, ASOCIADOS AL AMPLIFICADOR DE SALIDA (20), RESPONDEN A LA SEÑAL DE GANANCIA AJUSTADA Y FILTRADA PARA COMPARAR SU MAGNITUD CON UNOS NIVELES OBJETIVOS PREDETERMINADOS PARA DETERMINAR EL RITMO DEL CORAZON Y LA NECESIDAD DE CAMBIAR EL RITMO. EN CADA COMPARADOR HAY DOS NIVELES OBJETIVO PARA COMPARARLOS CON EL NIVEL DE LA SEÑAL DETECTADA A BASE DE MULTIPLEXAR LOS CAPACITORES CONMUTADOS. SE UTILIZA OTRO AMPLIFICADOR DE CAPACITORES CONMUTADOS (99) PARA GENERAR UN NIVEL DE TENSION DE REFERENCIA INSENSIBLE A LA TEMPERATURA, UNA TENSION DE ALIMENTACION Y ELEMENTOS DE CIRCUITO, PARA DERIVAR LOS NIVELESOBJETIVO PARA LLEVAR A CABO LA COMPARACION.
