Abstract

SE PRESENTA UN DISPOSITIVO COMPARADOR PARA COMPARAR NIVELES DE SEÑAL DE UNA PRIMERA Y SEGUNDA SEÑALES DE ENTRADA PARA PROPORCIONAR LAS SALIDAS DEL COMPARADOR RESULTANTES INDEPENDIENTEMENTE, DISPOSITIVO COMPARADOR CUYA CARACTERISTICA ES EVITAR LA PRODUCCION DE BAJOS NIVELES SIMULTANEOS DE LAS SEÑALES DEL COMPARADOR EN TODAS LAS CONDICIONES POSIBLES DE LAS SALIDAS DEL COMPARADOR. EL DISPOSITIVO COMPARADOR INCLUYE COMPARADORES PRIMERO Y SEGUNDO (12, 22) QUE INDEPENDIENTEMENTE EMITEN SALIDAS DE COMPARADOR RESULTANTES DEL NIVEL H Y NIVEL L COMO RESULTADO DE LA COMPARACION DE LOS NIVELES DE SEÑAL DE LA PRIMERA Y SEGUNDA SEÑAL DE ENTRADA TOMANDO UNA DE LAS SEÑALES DE ENTRADA COMO REFERENCIA, Y QUE TIENE CARACTERISTICAS DE DESVIO Y CARACTERISTICAS DE HISTERESIS DE MANERA QUE LAS SALIDAS DEL COMPARADOR, TANTO EL NIVEL H COMO EL NIVEL L SE PUEDEN DETERMINAR FIJAMENTE CUANDO LA PRIMERA Y SEGUNDA SEÑAL DE ENTRADA SON IGUALES UNA CON RESPECTO A LA OTRA. LA PRIMERA SEÑAL DE ENTRADA SE APLICA A UNO DE LOSTERMINALES DE ENTRADA DEL PRIMER COMPARADOR Y EL OTRO TERMINAL DE ENTRADA DEL SEGUNDO COMPARADOR CON DISTINTA POLARIDAD, Y LA SEGUNDA SEÑAL DE ENTRADA SE APLICA AL OTRO TERMINAL DE SEÑAL DE ENTRADA DEL PRIMER COMPARADOR Y UNO DE LOS TERMINALES DE ENTRADA DEL SEGUNDO COMPARADOR CON DIFERENTE POLARIDAD.
