Abstract

AMPLIFICADOR CONMUTADO PARA CIRCUITOS DE CODIFICACION POR IMPULSOS. ESTA CONSTITUIDO POR UN AMPLIFICADOR DIFERENCIAL (AMP1) REALIZADO CON DOS TRANSISTORES (T1 Y T1 ) Y QUE ES CONMUTADO POR LA SEÑAL PROCEDENTE DEL CIRCUITO (CSN). ESTA SEÑAL SE CARACTERIZA POR SER DE CORRIENTE CONSTANTE. LA SALIDA DEL AMPLIFICADOR (AMP1) ESTA EN PARALELO CON UN DISPOSITIVO DE CORTOCIRCUITO (BSC) CONTROLADO TAMBIEN POR LA UNIDAD (CSN) PARA ASEGURAR UN RECHAZO EN MODO COMUN ADECUADO. LA SALIDA DE ESTE AMPLIFICADOR SE LLEVA A OTRO AMPLIFICADOR DIFERENCIAL, DE DONDE SALE Y SE ALMACENA EN EL CONDENSADOR (C). ESTA SEÑAL ALMACENADA SE LLEVA A UN AMPLIFICADOR-COMPARADOR DE ALTA IMPEDANCIA, QUE CONVIERTE LA TENSION DEL CONDENSADOR (C) EN CORRIENTE PARA ALIMENTAR EL CONVERTIDOR ANALOGICO DIGITAL DE SALIDA.
