Abstract

OSCILADOR CONTROLADO, EN EL CUAL SE ELIMINA EL DESFASE, DEBIDO A LAS CAPACIDADES PARASITAS POR MEDIO DE UNA RED DE COMPENSACION. EL OSCILADOR (270) ESTA FORMADO POR UN AMPLIFICADOR (266) Y UN CIRCUITO RESONANTE (75). UNA RED DE CONTROL (254) CONSTITUIDA POR DOS AMPLIFICADORES DIFERENCIALES, QUE RECIBE LA SEÑAL OSCILATORIA POR MEDIO DEL DETECTOR (50), AJUSTA EN FASE LA SEÑAL QUE APARECE EN EL PUNTO (A). CADA UNO DE LOS COLECTORES DE LOS TRANSISTORES (201, 204) Y DE LA ETAPA DE CONTROL (254) LLEVA ASOCIADA UNA CAPACIDAD PARASITA DE DOS PICOFARADIOS QUE INTRODUCE UN DESFASE EN LA SEÑAL RESULTANTE EN EL PUNTO (A). ESTE DESFASE SE ELIMINA POR MEDIO DEL TRANSISTOR (257), QUE COMPENSA EL RETRASO INTRODUCIDO PRO DICHAS CAPACIDADES PARASITAS. DE APLICACION EN RECEPTORES DE TELEVISION EN COLOR.
