Design and Analysis of a SAW Gas Sensor Based LF RFID Tag in 0.18 um CMOS Process

Abstract

This paper presents the fully integrated low frequency-radio frequency identification (LF RFID) control logic circuitry for network gas sensing applications. Analog-to-digital-convertor (ADC) interfacing circuitry between RFID and the sensor are analyzed in 0.18 um CMOS process. A highly robust ADC is integrated to ensure the accurate gas detection in the surroundings.
