Abstract

EN UN GENERADOR EN DIENTE DE SIERRA VERTICAL (10,14) DE UN CIRCUITO DE DEFLEXION VERTICAL, UN PRIMER COMPARADOR (19) GENERA UNA SEÑAL DE SALIDA CUANDO UNA PORCION DE RETORNO (RETRACE) DE UNA SEÑAL EN DIENTE DE SIERRA (VRAMP) SE ENCUENTRA EM UNA PRIMERA MAGNITUD (VLOW) PARA INICIAR UNA PORCION DE TRAZA VERTICAL DE LA SEÑAL EN DIENTE DE SIERRA. UN AMPLIFICADOR (23) QUE RESPONDE A LA SEÑAL EN DIENTE DE SIERRA GENERA UNA CORRIENTE DE REALIMENTACION (IOUT) EN UN MOMENTO (H. LINE 210, FIG.2C) EN QUE OCURRE MAS DE LA MITAD DE LA LONGITUD DE LA PORCION DE TRAZA VERTICAL DESPUES DE QUE SE HAYA INICIADO LA TRAZA VERTICAL. LA CORRIENTE DE REALIMENTACION SE ENCUENTRA ACOPLADA A UN CAPACITOR (22) PARA CREAR UNA TENSION DEL CAPACITOR (VAGC). LA TENSION DEL CAPACITOR SE APLICA POR MEDIO DE UN CONVERTIDOR DE TENSION A CORRIENTE (21) A UN CAPACITOR INTEGRADOR (14) PARA CREAR EN EL CAPACITOR INTEGRADOR LA PORCION DE TRAZA DE LA SEÑAL EN DIENTE DE SIERRA.
