Abstract

EN UN CIRCUITO CONVERTIDOR CONSISTIENDO EN UN PRIMER TRANSISTOR (T11), EN CUYA BASE PUEDE SER APLICADA UNA SEÑAL DE ENTRADA, UN SEGUNDO TRANSISTOR (T12) DE FORMA COMPLEMENTARIA AL PRIMERO (T11), CUYA BASE ESTA CONECTADA AL EMISOR DEL PRIMER TRANSISTOR (T11) Y CUYO EMISOR ESTA CONECTADO A LA TERMINAL (B) DE SALIDA POR MEDIO DE UNA PRIMERA RESISTENCIA (R1), Y CON UN CIRCUITO (T13, T14) DE SUMINISTRO DE CORRIENTE QUE CONTROLA EL FLUJO DE CORRIENTE A TRAVES DE LA VIA DE PASO EMISOR-COLECTOR DE DOS TRANSISTORES (T11, T12), ES POSIBLE OBTENER UNA RESISTENCIA DE SALIDA VIRTUALMENTE CERO A TRAVES DE UNA SEGUNDA RESISTENCIA (R2) CONECTADA AL EMISOR DEL PRIMER TRANSISTOR (T11) QUE ESTA CONECTADA MEDIANTE LA CORRIENTE COLECTOR-EMISOR DEL PRIMER TRANSISTOR (T11) A LA BASE DEL SEGUNDO TRANSISTOR (T12). ES ESPACIALMENTE VENTAJOSO SI LOS TRANSISTORES DE CORRIENTE ESPECULAR DISPONEN DE LA MISMA POLARIDAD QUE EL PRIMERO O EL SEGUNDO TRANSISTOR (T11; T12) LOCALIZADOS EN EL CIRCUITO HACIA LOS CUALES FLUYE LAMISMA CORRIENTE.
