Abstract

THERE IS DISCLOSED A RFID READER DEVICE (10) THAT IS CONFIGURED WITH FEW ELEMENTS FOR THE AMPLIFIER CIRCUIT WHEREBY AN INTERROGATION ELECTRIC WAVE IS SEND-OUT AND ALSO ANALYZES THE RECEIVED RESPONSE WAVE FROM THE CONTACTLESS TAG. THE RFID READER DEVICE (10) HAS A DETECTION CIRCUIT (12) FOR DETECTING THE RECEIVED RESPONSE WAVE BY WAY OF AN ANTENNA (11) FROM THE CONTACTLESS TAG, AND OUTPUTTED AS RF BASE BAND SIGNAL. FURTHER, THE RFID READER DEVICE HAS AMPLIFIER CIRCUIT (13) THAT AMPLIFIES THE RF BASE BAND SIGNAL, AND OUTPUTTED AS LOGIC LEVEL RF OUTPUT SIGNAL. FURTHER, THE DEVICE HAS A CENTRAL PROCESSING UNIT (14) WHICH EXTRACTS THE IDENTIFICATION INFORMATION IN THE CONTACTLESS TAG FROM THE RF OUTPUT SIGNAL. THE AMPLIFIER CIRCUIT (13) IS CONFIGURED BASED ON RF BASE BAND SIGNAL IN THE INPUT TERMINAL, CORRECTOR AS AMPLIFIER OUTPUT TERMINAL, MULTI-STAGE AMPLIFIER (301) WHICH IS MADE BY A COMBINATION OF TRANSISTOR WITH EMITTER, PARALLEL-RESONANCE CIRCUIT (302) CONFIGURED AS PARALLEL CIRCUIT THAT COMPRISES OF INDUCTANCE AND CONDENSER CONNECTED TO THE CORRECTOR. THE MOST ILLUSTRATIVE FIGURE IS FIGURE 3
