Abstract

MULTIPLICADOR ANALOGICO CON MOSFETS. PRESENTA MEDIOS LINEALES DE MOSFET DE RESISTIVIDAD VARIABLE PARA HACER VARIAR LINEALMENTE LA INTENSIDAD "I" DE SALIDA EN FUNCION DE UNA TENSION SIMETRICA DE ENTRADA PROCEDENTE DE FUENTES "V2" Y "-V2" DE TENSION Y UNA TENSION DE ENTRADA PROCEDENTE DE UNA FUENTE "V1" DE TENSION DE ENTRADA ASOCIADA OPERATIVAMENTE CON LA TENSION SIMETRICA DE ENTRADA PROCEDENTE DE LAS FUENTES "V2" Y "-V2" DE TENSION, TENIENDO LOS MEDIOS LINEALES DE MOSFET DE RESISTIVIDAD VARIABLE UN NODO "A" PARA PRODUCIR A SU TRAVES LA INTENSIDAD "I" DE SALIDA VARIADA. LA UNIDAD AMPLIFICADORA OPERACIONAL INCLUYE ADEMAS UN ELEMENTO "Z" DE REALIMENTACION CONECTADO ENTRE EL TERMINAL DE ENTRADA DE INVERSION Y EL TERMINAL DE SALIDA DEL AMPLIFICADOR OPERACIONAL "U", PRODUCIENDO EL TERMINAL DE SALIDA UNA TENSION "VO". APLICABLE, PARTICULARMENTE, PARA OBTENER HIBRIDOS ANALOGICO-DIGITALES DE UNA SINAPSIS NEURAL ARTIFICIAL.
