A passive UHF RFID pressure sensor tag with a 7.27 bit and 5.47pJ capacitive sensor interface

Abstract

A full passive UHF pressure RFID tag is presented in this work. Special attention is paid to the novel capacitive sensor-interface and the analog FE which were designed and implemented on a low cost 0.35µm standard CMOS technology. The characterization of the fabricated sensor interface connected to a pressure MEMS transducer shows a fully digital output… (More)
