Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA AJUSTE DE UN CIRCUITO RECEPTOR OSCILANTE DE UN TRANSPONDEDOR EN UN SISTEMA RFID CON RESPECTO A LA RESONANCIA DE FRECUENCIA DE UNA SEÑAL DE SOLICITUD GENERADA MEDIANTE UN APARATO DE LECTURA, COMPRENDIENDO EL CIRCUITO RECEPTOR OSCILANTE AL MENOS UNA CAPACITANCIA INDUCTIVA ESPECIFICA Y AL MENOS UNA CAPACIDAD HABITUAL. JUSTO DESPUES DE QUE LA SEÑAL DE SOLICITUD HAYA SIDO RECIBIDA LOS CONDENSADORES SON CONECTADOS GRADUALMENTE A LAS CAPACIDADES HABITUALES HASTA QUE LA SEÑAL RECTIFICADA Y SUAVIZADA TOMA UN VALOR DE TENSION MAXIMO. ESTE EQUILIBRADO AUTOMATICO ACTIVO TIENE LUGAR CADA VEZ QUE ES INICIALIZADO EL TRANSPONDEDOR, PERO PUEDE SER TAMBIEN DISPARADO MEDIANTE UNA SECUENCIA ESPECIAL TRANSMITIDA DESDE EL APARATO DE LECTURA AL TRANSPONDEDOR.
