A Review of Implementing ADC in RFID Sensor

الملخص EN

The general considerations to design a sensor interface for passive RFID tags are discussed.

This way, power and timing constraints imposed by ISO/IEC 15693 and ISO/IEC 14443 standards to HF RFID tags are explored.

A generic multisensor interface is proposed and a survey analysis on the most suitable analog-to-digital converters for passive RFID sensing applications is reported.

The most appropriate converter type and architecture are suggested.

At the end, a specific sensor interface for carbon nanotube gas sensors is proposed and a brief discussion about its implemented circuits and preliminary results is made.
