Abstract

CIRCUITO INVERSOR DE POLARIDAD PARA INVERTIR LA POLARIDAD DE LOS CONDUCTORES (LI0, LI1) DE UNA LINEA DE TELECOMUNICACION. ESTE CIRCUITO INCLUYE UN CIRCUITO DE REFERENCIA QUE TIENE DOS SALIDAS (JP1, JP2) EN LAS CUALES APARECEN RESPECTIVAMENTE LAS TENSIONES DE REFERENCIA V+ -X Y VEET+X, ASI COMO UN CIRCUITO COMPUERTA CAPAZ DE CONECTAR CADA UNA DE LAS SALIDAS DEL CIRCUITO DE REFERENCIA A UNA DE LAS SALIDAS SELECCIONADAS (VTI, VRI) DEL CIRCUITO A TRAVES DE LOS DIODOS POLARIZADOS DIRECTAMENTE (P1, N4, N17, N15, N16) Y UNA RESISTENCIA (R36) PARA COMPENSAR LA CAIDA DE TENSION EN ESTOS DIODOS.
