Abstract

UNA SEÑAL DE VIDEO SE UNE DESDE UNA SALIDA DDE UN AMPLIFICADOR DRIVER DE UNA PANTALLA (20) A UN DISPOSITIVO DE IMAGEN (35) MEDIANTE UNA RED DE UNION (26) QUE INCLUYE TRANSISTORES SEGUIDORES EMISOR EN CASCADA (41,42) DEL CONDUCTIVIDAD OPUESTA. LOS DIODOS PRIMERO (43) Y SEGUNDO (44) SE CONECTAN RESPECTIVAMENTE A TRAVES DE LAS UNIONES BASE-EMISOR DE CADA TRANSISTOR Y SON POLARIZADOS POR CONDUCCION DE CORRIENTE DELANTERA EN UNA DIRECCION OPUESTA A LA DELA UNION BASE-EMISOR ASOCIADA. LA RED DE UNION SIGNIFICATIVAMENTE REDUCE EL VALOR DE LA CAPACIDAD DE LA PANTALLA COMO LA PRESENTADA A LA SALIDA DEL AMPLIFICADOR DEL DRIVER, QUE MEJORA LA RESPUESTA TRANSITORIA DE SEÑAL DE VIDEO POSITIVA Y NEGATIVA.
