Abstract

EL MONTAJE ESTA PENSADO PARA PROCESAR SEÑALES DE SENSOR SUMINISTRADAS POR UN SENSOR DE RESISTENCIA (20) EL CUAL AL SER SUMINISTRADO CON UNA SEÑAL DE ENERGIA (V), GENERA UN EFECTO DE MEDICION REPRESENTANDO LA DEPENDENCIA DE LA RESISTENCIA ELECTRICA EN EL VALOR MEDIDO COMO UNA REACCION A LA EFECTUADA DE UN VALOR FISICO MEDIDO. COMPRENDE UN CIRCUITO DE PROCESAMIENTO DE SEÑAL (2) QUE FUNCIONA EN EL PRINCIPIO DE TRANSPORTE DE CARGA O CUANTIFICADO A TRAVES DE ESTRUCTURAS DE CAPACITADOR-INTERRUPTOR. EL CIRCUITO DE PROCESO DE SEÑAL (2) PROPORCIONA UN BALANCE DE CARGA A TRAVES DE UNA INTEGRACION OPUESTA MUTUA EN GRUPOS DE CARGA DE MEDICION QUE DEPENDEN DEL EFECTO DE MEDICION Y SUMINISTRAN UNA SEÑAL DE SALIDA ANALOGA (U SUB A) CORRESPONDIENTE AL RESULTADO DE LA INTEGRACION. EL SUMINISTRO DE CARGA AL SENSOR ESTA AFECTADO POR LA REALIMENTACION DE LA SEÑAL DE SALIDA ANALOGA O UNA SEÑAL DE REALIMENTACION CON UNA RELACION FIJA A ESTO PARA ALCANZAR EL BALANCE DE CARGA. LA SEÑAL DE CARGA ANALOGA ESTA REGULADA POR ESTA REALIMENTACION DE TAL FORMA QUE ES PROPORCIONAL AL RESULTADO DE LA MEDICION.
