Abstract

EL CIRCUITO GENERADOR DE CORRIENTE ES INDEPENDIENTE DE LAS VARIACIONES DE TEMPERATURA Y DE LAS FLUCTUACIONES DE SUMINISTRO DE ENERGIA. INCLUYE LA CONEXION EN SERIE DE UNA FUENTE MCR PRINCIPAL DE CORRIENTE, QUE GENERA UNA CORRIENTE DE REFERENCIA IREF PARA GENERAR VREF Y, CONSECUENTEMENTE, SE NECESITA UNA FUENTE AUXILIAR DE CORRIENTE ACS PARA ACTIVAR EL CIRCUITO GENERADOR DE CORRIENTE. ACS INCLUYE UNA FUENTE DE CORRIENTE CS Y UNA FASE DE REGULACION RS PARA DESACTIVAR CS DESPUES DE LA ACTIVACION. RS INCLUYE UNA DERIVACION M2R2 DONDE UNA CORRIENTE IGUAL A IREF FLUYE Y DESACTIVA CS, SEGUN EL VALOR DE IREF. CM REALIZA LA DISTRIBUCION DE IREF SOBRE UN CIRCUITO INTEGRADO (NO REPRESENTADO) Y A VRS.
