Abstract
EN UN CIRCUITO INTEGRADO CON UN TRANSISTOR DE COLECTOR ABIERTO CONFORMADO COMO TRANSISTOR NPN, EL COLECTOR DEL TRANSISTOR DE COLECTOR ABIERTO SE CONECTA: POR UNA RESISTENCIA DE COLECTOR, PREFERENTEMENTE DE BAJO VALOR OHMICO, A UNA SALIDA DE COLECTOR ABIERTA DEL CIRCUITO, EN LA CUAL HAY UNA TENSION DE SALIDA; Y POR UN DIODO ANTIPARASITOS, QUE CON VALORES POSITIVOS DE LA TENSION DE SALIDA SE CONECTA EN SENTIDO DEL BLOQUEO, A UNA TOMA DE MASA DEL CIRCUITO. EL EMISOR DEL TRANSISTOR DE COLECTOR ABIERTO ESTA CONECTADO A LA TOMA DE MASA DEL CIRCUITO Y LA BASE DEL TRANSISTOR DE COLECTOR ABIERTO ESTA UNIDA A UNA FUENTE DE CORRIENTE DE BASE, QUE GENERA UNA CORRIENTE DE BASE. ANTE UN VALOR DE LA TENSION DE SALIDA QUE SEA INFERIOR A UN VALOR NEGATIVO DE LA TENSION UMBRAL, EL TRANSISTOR DE COLECTOR ABIERTO SE CONECTA A UN ESTADO DE CONDUCCION INVERSA POR LA CORRIENTE DE BASE, Y EN LA RESISTENCIA DEL COLECTOR SE ORIGINA UNA CAIDA DE TENSION, CUYO VALOR ES TAN GRANDE QUE EL DIODO ANTIPARASITOS PERMANECE CONECTADO EN EL SENTIDO DEL BLOQUEO.
