Abstract

UN CIRCUITO DE GRAN IMPEDANCIA COMPRENDE UN PAR DE CIRCUITOS COMPUESTOS POR UN PRIMER TRANSISTOR Y UN SEGUNDO TRANSISTOR Y UN CIRCUITO TAMPON. COMPRENDE UN PAR DE TRANSISTORES DE TIPO NPN COMPUESTO DE UNA CONEXION EN CASCADA DE TRANSISTORES DE TIPO NPN Y UN PAR DE TRANSISTORES DE TIPO PNP COMPUESTOS DE UNA CONEXION EN CASCADA DE TRANSISTORES DE TIPO PNP, Y BASES DE TRANSISTORES DE TIPO NPN Y BASES DE TRANSISTORES DE TIPO PNP QUE CORRESPONDEN RESPECTIVAMENTE A LOS TRANSISTORES DE TIPOS NPN ESTAN CONECTADOS UNO A OTROS., RESPECTIVAMENTE DE MANERA A CONSTITUIR CIRCUITOS DE ESPEJO DE CORRIENTE. UNA SALIDA DEL CIRCUITO DE PAR DIFERENCIAL ESTA CONECTADA A UN PUNTO DE CONEXION EN CASCADA DEL PAR DE TRANSISTORES DE TIPO NPN, Y UN EMISOR DE UN TRANSISTOR DE TIPO NPN COMPRENDIDO EN EL PAR DE TRANSISTORES DE TIPO NPN SE CONECTA A TRAVES DE TIERRA A UNA FUENTE E CORRIENTE CONSTANTE, Y EL EMISOR SE CONECTA A LAS BASES DEL PRIMER TRANSISTOR Y EL SEGUNDO TRANSITO A TRAVES DE REOSTATOS, RESPECTIVAMENTE. CONSIGUIENTEMENTE, LA SALIDA DEL CIRCUITO DE PAR DIFERENCIAL SE REALIMENTA EN ENTRADA DEL CIRCUITO DE PAR DIFERENCIA POR EJEMPLO LAS BASES DEL PRIMER TRANSISTOR Y EL SEGUNDO TRANSISTOR COMO CORRIENTES DE BASE.
