Abstract

COMPARADORES DE CRUZAMIENTO CERO CON VALIDEZ UMBRAL PARA CIRCUITOS DE RECUPERACION DE ONDA PORTADORA Y DE RECUPERACION DE TEMPORIZACION DE UN SISTEMA DE TRANSMISION DE DATOS DIGITAL. COMPRENDE UN AMPLIFICADOR DIFERENCIAL QUE TIENE LA SEÑAL DE ENTRADA ALIMENTADA CON UNA POLARIDAD OPUESTA A LA POLARIDAD CON RESPECTO A CERO DE LA SEÑAL DE ENTRADA; UNA REALIMENTACION CONSISTENTE EN DOS DISPOSITIVOS RESISTIVOS CONECTADOS EN SERIE EN LA SALIDA DEL COMPARADOR Y UNA REFERENCIA DE VOLTAJE CERO CON LA SEGUNDA ENTRADA DEL COMPARADOR CONECTADA A LA UNION DE LOS DISPOSITIVOS RESISTIVOS. CADA COMPARADOR GENERA UNA SEÑAL DE SALIDA CUANDO UNA SEÑAL DE ENTRADA CRUZA EL PUNTO CERO, BAJO LA CONDICION DE QUE LA EXCURSION DE LA SEÑAL DE ENTRADA HAYA SUPERADO UNA SEÑAL UMBRAL DE REFERENCIA DURANTE EL SEMICIRCULO ANTERIOR.
