Abstract

SE PRESENTA UN AMPLIFICADOR (10) QUE TIENE AL MENOS VARIAS ETAPAS ACTIVADAS SOLAMENTE A UNO DE LOS DOS ESTADOS BINIVEL CONTROLADO EN RESPUESTA AL VALOR DE UNA FUENTE DE ENTRADA QUE EXCEDE UN UMBRAL PARA CADA ETAPA (40). CADA ETAPA TIENE UN UMBRAL DIFERENTE. LOS UMBRALES Y LA FUENTE ESTAN DISPUESTOS DE FORMA QUE LAS ETAPAS CAMBIEN ENTRE LOS ESTADOS BINIVEL A MEDIDA QUE CAMBIA EL VALOR DE LA FUENTE CON RELACION A LOS UMBRALES DE LAS DIFERENTES ETAPAS. LAS SALIDAS BINIVEL DE LAS ETAPAS SE SUMAN JUNTAS. LOS VALORES DE LOS UMBRALES VARIAN DE FORMA CONTINUA EN UNA PEQUEÑA CANTIDAD EN RELACION A UN VALOR MAXIMO PREDETERMINADO PARA LA FUENTE EN RESPUESTA A UNA FUENTE DE RUIDO QUE ES INDEPENDIENTE A LA FUENTE DE SEÑAL. UNA FUENTE DE ALIMENTACION PARA LAS ETAPAS INCLUYE UN CONVERTIDOR CORRIENTE ALTERNACORRIENTE CONTINUA QUE TIENE BOBINADOS PRIMARIOS PLURALES (48, 50) Y VARIOS BOBINADOS SECUNDARIOS (52.2 ... 52.(M-2), 52.(M)), UNO PARA CADA UNA DE LAS ETAPAS. LOS BOBINADOS SE ACOPLAN JUNTOS DE FORMA QUE EN TODO MOMENTO LA CARGA DE LOS BOBINADOS PRIMARIOS POR LOS BOBINADOS SECUNDARIOS COMO RESULTADO DE LA ACTIVACION DE LAS ETAPAS DE SALIDA SEA APROXIMADAMENTE IGUAL. LAS ETAPAS (40) SE CONTROLAN DE MANERA QUE LA SUMA DE LAS SALIDAS DE LAS ETAPAS PERMANEZCA COMO UNA FUNCION PREDETERMINADA A PESAR DE LA CAIDA DE UNA O DE UNAS POCAS ETAPAS.
