Abstract

EN CIRCUITOS INTEGRADOS, QUE CONTIENEN UN AMPLIFICADOR PARA SEÑALES ANALOGICAS, P.J. EN CIRCUITOS DE REGULACION, A UNAS FRECUENCIAS ELEVADAS APARECEN DEFASAJES. PARA CONTRARRESTAR LAS OSCILACIONES NO CONTROLADAS CONDICIONADAS POR ELLO, CON AYUDA DE UN CONDENSADOR DE COMPENSACION DE LA RESPUESTA DE FRECUENCIA SE MODIFICA LA RESPUESTA DE FASE Y DE AMPLITUD. EL VALOR DE ESTE CONDENSADOR ES PROPORCIONAL A LA AMPLIFICACION. LOS CONDENSADORES INTEGRADOS NECESITAN, SIN EMBARGO, UNA GRAN SUPERFICIE DE CHIP. MEDIANTE LA INSERCION DE UN VALOR DE CONTROL (76) NO REGULADO, QUE CORRESPONDE CASI AL VALOR TEORICO (79), EL AMPLIFICADOR DE ERRORES (71) DEL CIRCUITO DE REGULACION TIENE SUFICIENTE CON UNA AMPLIFICACION PEQUEÑA. LA ALIMENTACION NEGATIVA PUEDE FALLAR POR ELLO MENOS Y SE REDUCE CORRESPONDIENTEMENTE EL VALOR NECESARIO DEL CONDENSADOR DE COMPENSACION DE LA RESPUESTA DE FRECUENCIA Y LA SUPERFICIE DE CHIP PARA ELLO NECESARIA. PARA AMPLIFICADORES ANALOGICOS INTEGRADOS.
