Abstract
CIRCUITO DETECTOR DE COLISIONES EN CADENA DE DOS PARA USAR CON UN TRANSCEPTOR DE DATOS CODIFICADOS SEGUN STARIAN QUE INCLUYE UN COMPARADOR DE TENSION CON UNA ENTRADA DE INVERSION, UNA ENTRADA DE NO INVERSION Y UNA SALIDA. LA ENTRADA DE INVERSION DEL COMPARADOR DE TENSION ES SENSIBLE A LOS VOLTAJES DE SALIDA DIFERENCIALES DESDE UN ACCIONADOR DE LINEA DIFERENCIAL Y LOS VOLTAJES DE PICO TRANSITORIOS DESDE EL PRIMARIO DE UN TRANSFORMADOR DE AISLAMIENTO. UN CONDENSADOR DE CARGA SE CONECTA A LA ENTRADA DE NO INVERSION DEL COMPARADOR DE VOLTAJE. EL CONDENSADOR SE CARGA AL VOLTAJE DE REFERENCIA QUE ES DIRECTAMENTE PROPORCIONAL AL VOLTAJE PICO DE LOS VOLTAJES DE SALIDA DIFERENCIALES. LA SALIDA DEL COMPARADOR DE VOLTAJE PROVEE UNA SEÑAL DE DETECCION DE COLISION INTERNA QUE ES INTERRUMPIDA DESDE UN NIVEL LOGICO ALTO A UN NIVEL LOGICO BAJO HASTA QUE TENGA LUGAR UNA COLISION EN CADENA DE DOS.
