Abstract

CONVERTIDOR ANALOGICO-DIGITAL PARALELO. DISPONE DE P=2>R-1 COMPARADORES (DL ... DP), DONDE R ES EL NUMERO DE BITS DE LA SEÑAL DE SALIDA DEL CONVERTIDOR, DISMINUIDO EN UNA UNIDAD. LA SEÑAL ANALOGICA SE APLICA A LAS ENTRADAS APROPIADAS DEL COMPARADOR A TRAVES DE UNA RESISTENCIA (R) QUE INTERCONECTA LOS COLECTORES DE DOS TRANSISTORES (T1, T2) CONECTADOS A MODO DE AMPLIFICADOR DIFERENCIAL, Y QUE TIENE UNA FUENTE DE CORRIENTE CONSTANTE (KQ) EN EL CIRCUITO EMISOR. LA BASE DE UNO DE LOS TRANSISTORES ESTA A POTENCIAL FIJO (UC), Y LA BASE DEL OTRO TRANSISTOR ES ALIMENTADA CON UNA SEÑAL DE RELOJ (F) CUYA FRECUENCIA ES LA MITAD DE LA SEÑAL DE RELOJ DEL CONVERTIDOR.
