Abstract

CIRCUITO DE CONTROL DE CONTINUA EN RECEPTORES DE DATOS A RAFAGAS. DEL TIPO DE LOS QUE REALIZAN UN DESACOPLO DE CONTINUA MEDIANTE CONDENSADOR, PARA AISLAR EL RECEPTOR DE ENTRADA DE ETAPAS POSTERIORES. APLICABLE EN SISTEMAS DE TRANSMISION DIGITAL A RAFAGAS POR FIBRA OPTICA EN BUCLES DE ABONADO. EL CIRCUITO DE LA INVENCION COMPRENDE UN RECEPTOR DE LINEA (1) QUE CONVIERTE LA SEÑAL RECIBIDA POR UN MEDIO DE TRANSMISION EN UNA SEÑAL ELECTRICA (S), UN CIRCUITO DE DESACOPLO DE CONTINUA (C, R1) Y UN PRIMER AMPLIFICADOR (A1). SE CARACTERIZA PORQUE COMPRENDE ADEMAS UN CIRCUITO DE CONTROL (2) QUE MIDE LA COMPONENTE CONTINUA EN EL NODO DE ENTRADA DEL PRIMER AMPLIFICADOR (A1) DURANTE LOS INSTANTES DE LA TRAMA EN LOS QUE NO SE RECIBE SEÑAL, Y UN GENERADOR DE CORRIENTE (I) QUE ENTREGA A DICHO NODO UNA CORRIENTE CUYO VALOR ES DETERMINADO POR EL CIRCUITO DE CONTROL (2), DE FORMA QUE COMPENSEN EL INCREMENTO DE TENSION PRODUCIDO EN EL CONDENSADOR DE DESACOPLO.
