Full ISO 11784/11785 compliant RFID reader in a programmable analog-digital, integrated circuit

Nowadays, powerful off-the-shelve System on Chip (SOC) ICs are available to implement complex communication or signal processing modules. In this work a programmable-analog, programmable-digital IC, is utilized to implement a fully compliant IS011784/11785 RFID reader module, working at 134.2 kHz. Several continuous time programmable gain amplifiers, switched capacitor filters, comparators, programmable timers, clock generators, and a rise CPU core, all them inside the SOC, are used for the signal decoding. The proposed RFID core is part of a handheld reader device, aimed at being used in cattle industry traceability.
